Hi all,
Version 9 contains following major changes:
- Clock nodes changed to use offsets instead of direct memory addresses
* of_iomap() no longer called by individual clock drivers
* "prcm-driver" provides regmap for accessing the registers based on
the offsets
* added support for regmaps to generic clock code
* added support for regmaps to clock code under mach-omap2
- Devicetree layout changed to be hierarchical: ocp->ip->clocks/clockdomains
* allows above mentioned offsets to be used
- Clock init mechanism changed completely, called now from prm_common.c,
see patch #38. This patch contains some rather nasty looking hackery so
if anybody has any idea how to make it cleaner, comments appreciated.
Otherwise it can be cleaned later once strict hwmod dependencies are
cleared and we don't need to do the early init hacks anymore.
- ti,mux-gate-clock type was killed, instead added support for
ti,composite-clock (see patch #08 for base + components in patches
#09 + #11 + #13)
Some minor changes also done:
- changed ti,autoidle-low to ti,invert-autoidle-bit
- ordering of patches changed to reflect merge locations
(drivers/clk, arch/arm/boot/dts, arch/arm/mach-omap2)
- maybe some others, too much code to track.... should have covered
most of the major comments from Paul though
Dependencies (included in the test branch):
- regmap: debugfs: Fix a boot time crash with early regmap init
- ARM: dts: OMAP5: Add mailbox dt node
- ARM: OMAP5/DRA7: realtime_counter: Configure CNTFRQ register(v4)
- clk: of: helper for determining number of parent clocks
Testing done:
- omap3-beagle: boot + suspend/resume (ret + off)
- omap4-panda-es: boot + suspend/resume
- omap5-uevm: boot
- dra7-evm: boot
- am335x-bone: boot

Previously, only direct register read/write was supported. Now a per-clock
regmap can be provided for same purpose, which allows the clock drivers
to access clock registers behind e.g. I2C bus.

+Binding for Texas Instruments DPLL clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped DPLL with usually two selectable input clocks
+(reference clock and bypass clock), with digital phase locked
+loop logic for multiplying the input clock to a desired output
+clock. This clock also typically supports different operation
+modes (locked, low power stop etc.) This binding has several
+sub-types, which effectively result in slightly different setup
+for the actual DPLL clock.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be one of:
+ "ti,omap3-dpll-clock",
+ "ti,omap3-dpll-core-clock",
+ "ti,omap3-dpll-per-clock",
+ "ti,omap3-dpll-per-j-type-clock",
+ "ti,omap4-dpll-clock",
+ "ti,omap4-dpll-x2-clock",
+ "ti,omap4-dpll-core-clock",
+ "ti,omap4-dpll-m4xen-clock",
+ "ti,omap4-dpll-j-type-clock",
+ "ti,am3-dpll-no-gate-clock",
+ "ti,am3-dpll-j-type-clock",
+ "ti,am3-dpll-no-gate-j-type-clock",
+ "ti,am3-dpll-clock",
+ "ti,am3-dpll-core-clock",
+ "ti,am3-dpll-x2-clock",
+
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks, first entry lists reference clock
+ and second entry bypass clock
+- reg : offsets for the register set for controlling the DPLL.
+ Registers are listed in following order:
+ "control" - contains the control register base address
+ "idlest" - contains the idle status register base address
+ "autoidle" - contains the autoidle register base address
+ "mult-div1" - contains the multiplier / divider register base address
+ ti,am3-* dpll types list the registers in the same order, except "autoidle"
+ register is left out as this hardware does not have it, e.g.:
+ reg = <0x40>, <0x50>, <0x60>;
+ results in following register map:
+ base + 0x40 - control
+ base + 0x50 - idlest
+ base + 0x60 - mult-div1
+
+Optional properties:
+- DPLL mode setting - defining any one or more of the following overrides
+ default setting.
+ - ti,low-power-stop : DPLL supports low power stop mode, gating output
+ - ti,low-power-bypass : DPLL output matches rate of parent bypass clock
+ - ti,lock : DPLL locks in programmed rate
+
+Examples:
+ dpll_core_ck: dpll_core_ck@44e00490 {
+ #clock-cells = <0>;
+ compatible = "ti,omap4-dpll-core-clock";
+ clocks = <&sys_clkin_ck>, <&sys_clkin_ck>;
+ reg = <0x490>, <0x45c>, <0x488>, <0x468>;
+ };
+
+ dpll2_ck: dpll2_ck@48004004 {
+ #clock-cells = <0>;
+ compatible = "ti,omap3-dpll-clock";
+ clocks = <&sys_ck>, <&dpll2_fck>;
+ ti,low-power-stop;
+ ti,low-power-bypass;
+ ti,lock;
+ reg = <0x4>, <0x24>, <0x34>, <0x40>;
+ };
+
+ dpll_core_ck: dpll_core_ck@44e00490 {
+ #clock-cells = <0>;
+ compatible = "ti,am3-dpll-core-clock";
+ clocks = <&sys_clkin_ck>, <&sys_clkin_ck>;

+Binding for Texas Instruments DPLL clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped DPLL with usually two selectable input clocks
+(reference clock and bypass clock), with digital phase locked
+loop logic for multiplying the input clock to a desired output
+clock. This clock also typically supports different operation
+modes (locked, low power stop etc.) This binding has several
+sub-types, which effectively result in slightly different setup
+for the actual DPLL clock.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be one of:
+ "ti,omap3-dpll-clock",
+ "ti,omap3-dpll-core-clock",
+ "ti,omap3-dpll-per-clock",
+ "ti,omap3-dpll-per-j-type-clock",
+ "ti,omap4-dpll-clock",
+ "ti,omap4-dpll-x2-clock",
+ "ti,omap4-dpll-core-clock",
+ "ti,omap4-dpll-m4xen-clock",
+ "ti,omap4-dpll-j-type-clock",
+ "ti,am3-dpll-no-gate-clock",
+ "ti,am3-dpll-j-type-clock",
+ "ti,am3-dpll-no-gate-j-type-clock",
+ "ti,am3-dpll-clock",
+ "ti,am3-dpll-core-clock",
+ "ti,am3-dpll-x2-clock",
+
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks, first entry lists reference clock
+ and second entry bypass clock
+- reg : offsets for the register set for controlling the DPLL.
+ Registers are listed in following order:
+ "control" - contains the control register base address
+ "idlest" - contains the idle status register base address
+ "autoidle" - contains the autoidle register base address
+ "mult-div1" - contains the multiplier / divider register base address
+ ti,am3-* dpll types list the registers in the same order, except "autoidle"
+ register is left out as this hardware does not have it, e.g.:
+ reg = <0x40>, <0x50>, <0x60>;
+ results in following register map:
+ base + 0x40 - control
+ base + 0x50 - idlest
+ base + 0x60 - mult-div1
+
+Optional properties:
+- DPLL mode setting - defining any one or more of the following overrides
+ default setting.
+ - ti,low-power-stop : DPLL supports low power stop mode, gating output
+ - ti,low-power-bypass : DPLL output matches rate of parent bypass clock
+ - ti,lock : DPLL locks in programmed rate
+
+Examples:
+ dpll_core_ck: dpll_core_ck at 44e00490 {
+ #clock-cells = <0>;
+ compatible = "ti,omap4-dpll-core-clock";
+ clocks = <&sys_clkin_ck>, <&sys_clkin_ck>;
+ reg = <0x490>, <0x45c>, <0x488>, <0x468>;
+ };
+
+ dpll2_ck: dpll2_ck at 48004004 {
+ #clock-cells = <0>;
+ compatible = "ti,omap3-dpll-clock";
+ clocks = <&sys_ck>, <&dpll2_fck>;
+ ti,low-power-stop;
+ ti,low-power-bypass;
+ ti,lock;
+ reg = <0x4>, <0x24>, <0x34>, <0x40>;
+ };
+
+ dpll_core_ck: dpll_core_ck at 44e00490 {
+ #clock-cells = <0>;
+ compatible = "ti,am3-dpll-core-clock";
+ clocks = <&sys_clkin_ck>, <&sys_clkin_ck>;
+ reg = <0x90>, <0x5c>, <0x68>;
+ };

Some devices require their clocks to be available with a specific
dev-id con-id mapping. With DT, the clocks can be found by default
only with their name, or alternatively through the device node of
the consumer. With drivers, that don't support DT fully yet, add
mechanism to register specific clock names.

ti_dt_clk_init_provider() can now be used to initialize the contents of
a single clock IP block. This parses all the clocks under the IP block
and calls the corresponding init function for them.

This is a multipurpose clock node, which contains support for multiple
sub-clocks. Uses basic composite clock type to implement the actual
functionality, and TI specific gate, mux and divider clocks.

+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped composite clock with multiple different sub-types;
+
+a multiplexer clock with multiple input clock signals or parents, one
+of which can be selected as output, this behaves exactly as [2]
+
+an adjustable clock rate divider, this behaves exactly as [3]
+
+a gating function which can be used to enable and disable the output
+clock, this behaves exactly as [4]
+
+The binding must provide a list of the component clocks that shall be
+merged to this clock. The component clocks shall be of one of the
+"ti,*composite*-clock" types.

This is a multipurpose clock node, which contains support for multiple
sub-clocks. Uses basic composite clock type to implement the actual
functionality, and TI specific gate, mux and divider clocks.

+Binding for TI divider clock
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped adjustable clock rate divider that does not gate and has
+only one input clock or parent. By default the value programmed into
+the register is one less than the actual divisor value. E.g:
+
+register value actual divisor value
+0 1
+1 2
+2 3
+
+This assumption may be modified by the following optional properties:
+
+ti,index-starts-at-one - valid divisor values start at 1, not the default
+of 0. E.g:
+register value actual divisor value
+1 1
+2 2
+3 3
+
+ti,index-power-of-two - valid divisor values are powers of two. E.g:
+register value actual divisor value
+0 1
+1 2
+2 4
+
+Additionally an array of valid dividers may be supplied like so:
+
+ dividers = <4>, <8>, <0>, <16>;
+
+Which will map the resulting values to a divisor table by their index:
+register value actual divisor value
+0 4
+1 8
+2 <invalid divisor, skipped>
+3 16
+
+Any zero value in this array means the corresponding bit-value is invalid
+and must not be used.
+
+The binding must also provide the register to control the divider and
+unless the divider array is provided, min and max dividers. Optionally
+the number of bits to shift that mask, if necessary. If the shift value
+is missing it is the same as supplying a zero shift.
+
+Required properties:
+- compatible : shall be "ti,divider-clock".
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link to phandle of parent clock
+- reg : offset for register controlling adjustable divider
+
+Optional properties:
+- clock-output-names : from common clock binding.
+- ti,dividers : array of integers defining divisors
+- ti,bit-shift : number of bits to shift the divider value, defaults to 0
+- ti,min-div : min divisor for dividing the input clock rate, only
+ needed if the first divisor is offset from the default value (1)
+- ti,max-div : max divisor for dividing the input clock rate, only needed
+ if ti,dividers is not defined.
+- ti,index-starts-at-one : valid divisor programming starts at 1, not zero
+- ti,index-power-of-two : valid divisor programming must be a power of two
+- ti,autoidle-shift : bit shift of the autoidle enable bit for the clock
+- ti,invert-autoidle-bit : autoidle is enabled by setting the bit to 0
+- ti,set-rate-parent : clk_set_rate is propagated to parent
+
+Examples:
+dpll_usb_m2_ck: dpll_usb_m2_ck@4a008190 {
+ #clock-cells = <0>;
+ compatible = "ti,divider-clock";

+Binding for TI divider clock
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped adjustable clock rate divider that does not gate and has
+only one input clock or parent. By default the value programmed into
+the register is one less than the actual divisor value. E.g:
+
+register value actual divisor value
+0 1
+1 2
+2 3
+
+This assumption may be modified by the following optional properties:
+
+ti,index-starts-at-one - valid divisor values start at 1, not the default
+of 0. E.g:
+register value actual divisor value
+1 1
+2 2
+3 3
+
+ti,index-power-of-two - valid divisor values are powers of two. E.g:
+register value actual divisor value
+0 1
+1 2
+2 4
+
+Additionally an array of valid dividers may be supplied like so:
+
+ dividers = <4>, <8>, <0>, <16>;
+
+Which will map the resulting values to a divisor table by their index:
+register value actual divisor value
+0 4
+1 8
+2 <invalid divisor, skipped>
+3 16
+
+Any zero value in this array means the corresponding bit-value is invalid
+and must not be used.
+
+The binding must also provide the register to control the divider and
+unless the divider array is provided, min and max dividers. Optionally
+the number of bits to shift that mask, if necessary. If the shift value
+is missing it is the same as supplying a zero shift.
+
+Required properties:
+- compatible : shall be "ti,divider-clock".
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link to phandle of parent clock
+- reg : offset for register controlling adjustable divider
+
+Optional properties:
+- clock-output-names : from common clock binding.
+- ti,dividers : array of integers defining divisors
+- ti,bit-shift : number of bits to shift the divider value, defaults to 0
+- ti,min-div : min divisor for dividing the input clock rate, only
+ needed if the first divisor is offset from the default value (1)

+ if ti,dividers is not defined.

+- ti,invert-autoidle-bit : autoidle is enabled by setting the bit to 0

This behaves exactly in similar manner to basic fixed-factor-clock, but
adds a few properties on top for handling clock hardware autoidling.

This behaves exactly in similar manner to basic fixed-factor-clock, but
adds a few properties on top for handling clock hardware autoidling.

Cc: linux-arm-kernel, devicetree
This patch adds support for TI specific gate clocks. These behave as basic
gate-clock, but have different ops / hw-ops for controlling the actual
gate, for example waiting until the clock is ready. Several sub-types
are supported:
- ti,gate-clock: basic gate clock with default ops/hwops
- ti,clkdm-gate-clock: clockdomain level gate control
- ti,dss-gate-clock: gate clock with DSS specific hardware handling
- ti,am35xx-gate-clock: gate clock with AM35xx specific hardware handling
- ti,hsdiv-gate-clock: gate clock with OMAP36xx hardware errata handling

+Binding for Texas Instruments gate clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. This clock is
+quite much similar to the basic gate-clock [2], however,
+it supports a number of additional features. If no register
+is provided for this clock, the code assumes that a clockdomain
+will be controlled instead and the corresponding hw-ops for
+that is used.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+[2] Documentation/devicetree/bindings/clock/gate-clock.txt
+[3] Documentation/devicetree/bindings/clock/ti/clockdomain.txt
+
+Required properties:
+- compatible : shall be one of:
+ "ti,gate-clock" - basic gate clock
+ "ti,wait-gate-clock" - gate clock which waits until clock is active before
+ returning from clk_enable()
+ "ti,dss-gate-clock" - gate clock with DSS specific hardware handling
+ "ti,am35xx-gate-clock" - gate clock with AM35xx specific hardware handling
+ "ti,clkdm-gate-clock" - clockdomain gate clock, which derives its functional
+ clock directly from a clockdomain, see [3] how
+ to map clockdomains properly
+ "ti,hsdiv-gate-clock" - gate clock with OMAP36xx specific hardware handling,
+ required for a hardware errata
+- #clock-cells : from common clock binding; shall be set to 0
+- clocks : link to phandle of parent clock
+- reg : offset for register controlling adjustable gate, not needed for
+ ti,clkdm-gate-clock type
+- ti,bit-shift : bit shift for programming the clock gate, not needed for
+ ti,clkdm-gate-clock type
+
+Optional properties:
+- ti,set-bit-to-disable : inverts default gate programming. Setting the bit
+ gates the clock and clearing the bit ungates the clock.
+
+Examples:
+ mmchs2_fck: mmchs2_fck@48004a00 {
+ #clock-cells = <0>;
+ compatible = "ti,gate-clock";
+ clocks = <&core_96m_fck>;

* [PATCHv9 11/43] CLK: TI: add support for gate clock
@ 2013-10-25 15:57 ` Tero Kristo

From: Tero Kristo @ 2013-10-25 15:57 UTC (permalink / raw)
To: linux-arm-kernel
This patch adds support for TI specific gate clocks. These behave as basic
gate-clock, but have different ops / hw-ops for controlling the actual
gate, for example waiting until the clock is ready. Several sub-types
are supported:
- ti,gate-clock: basic gate clock with default ops/hwops
- ti,clkdm-gate-clock: clockdomain level gate control
- ti,dss-gate-clock: gate clock with DSS specific hardware handling
- ti,am35xx-gate-clock: gate clock with AM35xx specific hardware handling
- ti,hsdiv-gate-clock: gate clock with OMAP36xx hardware errata handling

+Binding for Texas Instruments gate clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. This clock is
+quite much similar to the basic gate-clock [2], however,
+it supports a number of additional features. If no register
+is provided for this clock, the code assumes that a clockdomain
+will be controlled instead and the corresponding hw-ops for
+that is used.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+[2] Documentation/devicetree/bindings/clock/gate-clock.txt
+[3] Documentation/devicetree/bindings/clock/ti/clockdomain.txt
+
+Required properties:
+- compatible : shall be one of:
+ "ti,gate-clock" - basic gate clock
+ "ti,wait-gate-clock" - gate clock which waits until clock is active before
+ returning from clk_enable()
+ "ti,dss-gate-clock" - gate clock with DSS specific hardware handling
+ "ti,am35xx-gate-clock" - gate clock with AM35xx specific hardware handling
+ "ti,clkdm-gate-clock" - clockdomain gate clock, which derives its functional
+ clock directly from a clockdomain, see [3] how
+ to map clockdomains properly
+ "ti,hsdiv-gate-clock" - gate clock with OMAP36xx specific hardware handling,
+ required for a hardware errata
+- #clock-cells : from common clock binding; shall be set to 0
+- clocks : link to phandle of parent clock
+- reg : offset for register controlling adjustable gate, not needed for
+ ti,clkdm-gate-clock type
+- ti,bit-shift : bit shift for programming the clock gate, not needed for
+ ti,clkdm-gate-clock type
+
+Optional properties:
+- ti,set-bit-to-disable : inverts default gate programming. Setting the bit
+ gates the clock and clearing the bit ungates the clock.
+
+Examples:
+ mmchs2_fck: mmchs2_fck at 48004a00 {
+ #clock-cells = <0>;
+ compatible = "ti,gate-clock";
+ clocks = <&core_96m_fck>;

+ ti,bit-shift = <25>;
+ };

+ clocks = <&dpll4_m4x2_ck>;
+ reg = <0x48004e00 0x4>;
+ ti,bit-shift = <0>;
+ };
+

+Binding for TI mux clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped multiplexer with multiple input clock signals or
+parents, one of which can be selected as output. This clock does not
+gate or adjust the parent rate via a divider or multiplier.
+
+By default the "clocks" property lists the parents in the same order
+as they are programmed into the regster. E.g:
+
+ clocks = <&foo_clock>, <&bar_clock>, <&baz_clock>;
+
+results in programming the register as follows:
+
+register value selected parent clock
+0 foo_clock
+1 bar_clock
+2 baz_clock
+
+Some clock controller IPs do not allow a value of zero to be programmed
+into the register, instead indexing begins at 1. The optional property
+"index-starts-at-one" modified the scheme as follows:
+
+register value selected clock parent
+1 foo_clock
+2 bar_clock
+3 baz_clock
+
+The binding must provide the register to control the mux. Optionally
+the number of bits to shift the control field in the register can be
+supplied. If the shift value is missing it is the same as supplying
+a zero shift.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be "ti,mux-clock".
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks
+- reg : register offset for register controlling adjustable mux
+
+Optional properties:
+- ti,bit-shift : number of bits to shift the bit-mask, defaults to
+ 0 if not present
+- ti,index-starts-at-one : valid input select programming starts at 1, not
+ zero
+- ti,set-rate-parent : clk_set_rate is propagated to parent clock
+
+Examples:
+
+sys_clkin_ck: sys_clkin_ck@4a306110 {
+ #clock-cells = <0>;
+ compatible = "ti,mux-clock";
+ clocks = <&virt_12000000_ck>, <&virt_13000000_ck>, <&virt_16800000_ck>, <&virt_19200000_ck>, <&virt_26000000_ck>, <&virt_27000000_ck>, <&virt_38400000_ck>;
+ reg = <0x4a306110 0x4>;
+ ti,index-starts-at-one;
+};
+
+abe_dpll_bypass_clk_mux_ck: abe_dpll_bypass_clk_mux_ck@4a306108 {
+ #clock-cells = <0>;
+ compatible = "ti,mux-clock";

ti,mux-clock provides now a binding for basic mux support. This is just
using the basic clock type.

+Binding for TI mux clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped multiplexer with multiple input clock signals or
+parents, one of which can be selected as output. This clock does not
+gate or adjust the parent rate via a divider or multiplier.
+
+By default the "clocks" property lists the parents in the same order
+as they are programmed into the regster. E.g:
+
+ clocks = <&foo_clock>, <&bar_clock>, <&baz_clock>;
+
+results in programming the register as follows:
+
+register value selected parent clock
+0 foo_clock
+1 bar_clock
+2 baz_clock
+
+Some clock controller IPs do not allow a value of zero to be programmed
+into the register, instead indexing begins at 1. The optional property
+"index-starts-at-one" modified the scheme as follows:
+
+register value selected clock parent
+1 foo_clock
+2 bar_clock
+3 baz_clock
+
+The binding must provide the register to control the mux. Optionally
+the number of bits to shift the control field in the register can be
+supplied. If the shift value is missing it is the same as supplying
+a zero shift.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be "ti,mux-clock".
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks
+- reg : register offset for register controlling adjustable mux
+
+Optional properties:
+- ti,bit-shift : number of bits to shift the bit-mask, defaults to
+ 0 if not present
+- ti,index-starts-at-one : valid input select programming starts at 1, not
+ zero
+- ti,set-rate-parent : clk_set_rate is propagated to parent clock
+
+Examples:
+
+sys_clkin_ck: sys_clkin_ck at 4a306110 {
+ #clock-cells = <0>;
+ compatible = "ti,mux-clock";
+ clocks = <&virt_12000000_ck>, <&virt_13000000_ck>, <&virt_16800000_ck>, <&virt_19200000_ck>, <&virt_26000000_ck>, <&virt_27000000_ck>, <&virt_38400000_ck>;
+ reg = <0x4a306110 0x4>;
+ ti,index-starts-at-one;
+};
+
+abe_dpll_bypass_clk_mux_ck: abe_dpll_bypass_clk_mux_ck at 4a306108 {
+ #clock-cells = <0>;
+ compatible = "ti,mux-clock";
+ clocks = <&sys_clkin_ck>, <&sys_32k_ck>;
+ ti,bit-shift = <24>;

* [PATCHv9 17/43] CLK: TI: DRA7: Add APLL support

Cc: linux-arm-kernel, devicetree, J Keerthy
From: J Keerthy <j-keerthy@ti.com>
The patch adds support for DRA7 PCIe APLL. The APLL
sources the optional functional clocks for PCIe module.
APLL stands for Analog PLL. This is different when comapred
with DPLL meaning Digital PLL, the phase detection is done
using an analog circuit.

+Binding for Texas Instruments APLL clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped APLL with usually two selectable input clocks
+(reference clock and bypass clock), with analog phase locked
+loop logic for multiplying the input clock to a desired output
+clock. This clock also typically supports different operation
+modes (locked, low power stop etc.) APLL mostly behaves like
+a subtype of a DPLL [2], although a simplified one at that.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+[2] Documentation/devicetree/bindings/clock/ti/dpll.txt
+
+Required properties:
+- compatible : shall be "ti,dra7-apll-clock"
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks (clk-ref and clk-bypass)
+- reg : address and length of the register set for controlling the APLL.
+ It contains the information of registers in the following order:
+ "control" - contains the control register base address
+ "idlest" - contains the idlest register base address
+
+Examples:
+ apll_pcie_ck: apll_pcie_ck@4a008200 {
+ #clock-cells = <0>;
+ clocks = <&apll_pcie_in_clk_mux>, <&dpll_pcie_ref_ck>;

* [PATCHv9 17/43] CLK: TI: DRA7: Add APLL support
@ 2013-10-25 15:57 ` Tero Kristo
0 siblings, 0 replies; 212+ messages in thread
From: Tero Kristo @ 2013-10-25 15:57 UTC (permalink / raw)
To: linux-arm-kernel
From: J Keerthy <j-keerthy@ti.com>
The patch adds support for DRA7 PCIe APLL. The APLL
sources the optional functional clocks for PCIe module.
APLL stands for Analog PLL. This is different when comapred
with DPLL meaning Digital PLL, the phase detection is done
using an analog circuit.

+Binding for Texas Instruments APLL clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped APLL with usually two selectable input clocks
+(reference clock and bypass clock), with analog phase locked
+loop logic for multiplying the input clock to a desired output
+clock. This clock also typically supports different operation
+modes (locked, low power stop etc.) APLL mostly behaves like
+a subtype of a DPLL [2], although a simplified one at that.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+[2] Documentation/devicetree/bindings/clock/ti/dpll.txt
+
+Required properties:
+- compatible : shall be "ti,dra7-apll-clock"
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks (clk-ref and clk-bypass)
+- reg : address and length of the register set for controlling the APLL.
+ It contains the information of registers in the following order:
+ "control" - contains the control register base address
+ "idlest" - contains the idlest register base address
+
+Examples:
+ apll_pcie_ck: apll_pcie_ck at 4a008200 {
+ #clock-cells = <0>;
+ clocks = <&apll_pcie_in_clk_mux>, <&dpll_pcie_ref_ck>;
+ reg = <0x4a00821c 0x4>, <0x4a008220 0x4>;
+ compatible = "ti,dra7-apll-clock";
+ };

clk-33xx.c now contains the clock init functionality for am33xx, including
DT clock registration and adding of static clkdev entries.
This patch also moves the omap2_clk_enable_init_clocks declaration to
the driver include, as this is needed by the am33xx clock init code.

+Binding for Texas Instruments interface clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. This clock is
+quite much similar to the basic gate-clock [2], however,
+it supports a number of additional features, including
+companion clock finding (match corresponding functional gate
+clock) and hardware autoidle enable / disable.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+[2] Documentation/devicetree/bindings/clock/gate-clock.txt
+
+Required properties:
+- compatible : shall be one of:
+ "ti,omap3-interface-clock" - basic OMAP3 interface clock
+ "ti,omap3-no-wait-interface-clock" - interface clock which has no hardware
+ capability for waiting clock to be ready
+ "ti,omap3-hsotgusb-interface-clock" - interface clock with USB specific HW
+ handling
+ "ti,omap3-dss-interface-clock" - interface clock with DSS specific HW handling
+ "ti,omap3-ssi-interface-clock" - interface clock with SSI specific HW handling
+ "ti,am35xx-interface-clock" - interface clock with AM35xx specific HW handling
+- #clock-cells : from common clock binding; shall be set to 0
+- clocks : link to phandle of parent clock
+- reg : base address for the control register
+
+Optional properties:
+- ti,bit-shift : bit shift for the bit enabling/disabling the clock (default 0)
+
+Examples:
+ aes1_ick: aes1_ick@48004a14 {
+ #clock-cells = <0>;
+ compatible = "ti,omap3-interface-clock";
+ clocks = <&security_l4_ick2>;
+ reg = <0x48004a14 0x4>;
+ ti,bit-shift = <3>;

+ clocks = <&l4_ick>;
+ reg = <0x48004f10 0x4>;

* [PATCHv9 23/43] ARM: dts: omap4 clock data
2013-10-25 15:56 ` Tero Kristo

To: linux-omap, paul, tony, nm, bcousson, rnayak, mturquette
Cc: linux-arm-kernel, devicetree
This patch creates a unique node for each clock in the OMAP4 power,
reset and clock manager (PRCM). OMAP443x and OMAP446x have slightly
different clock tree which is taken into account in the data.

* [PATCHv9 23/43] ARM: dts: omap4 clock data
@ 2013-10-25 15:57 ` Tero Kristo

From: Tero Kristo @ 2013-10-25 15:57 UTC (permalink / raw)
To: linux-arm-kernel
This patch creates a unique node for each clock in the OMAP4 power,
reset and clock manager (PRCM). OMAP443x and OMAP446x have slightly
different clock tree which is taken into account in the data.

This patch creates a unique node for each clock in the DRA7 power,
reset and clock manager (PRCM).
TODO: apll_pcie clock node is still a dummy in this version, and
proper support for the APLL should be added.

* [PATCHv9 25/43] ARM: dts: dra7 clock data
@ 2013-10-25 15:57 ` Tero Kristo

To: linux-arm-kernel
This patch creates a unique node for each clock in the DRA7 power,
reset and clock manager (PRCM).
TODO: apll_pcie clock node is still a dummy in this version, and
proper support for the APLL should be added.

* [PATCHv9 32/43] ARM: dts: AM35xx: use DT clock data

AM35xx now uses the clock data from device tree. Most of the data is
shared with OMAP3xxx, but as there is some delta, a new base .dtsi
file is also created for the SoC.

Using regmap is required for isolating the actual memory access from
the clock code. Now, the driver providing the support for the clock IP
block can provide a regmap for this purpose.

* [PATCHv9 35/43] ARM: OMAP2+: clock: use driver API instead of direct memory read/write

Clock nodes shall use the services provided by underlying drivers to access
the hardware registers instead of direct memory read/write. Thus, change
all the code to use the new omap2_clk_readl / omap2_clk_writel APIs for this.

* [PATCHv9 35/43] ARM: OMAP2+: clock: use driver API instead of direct memory read/write
@ 2013-10-25 15:57 ` Tero Kristo

From: Tero Kristo @ 2013-10-25 15:57 UTC (permalink / raw)
To: linux-arm-kernel
Clock nodes shall use the services provided by underlying drivers to access
the hardware registers instead of direct memory read/write. Thus, change
all the code to use the new omap2_clk_readl / omap2_clk_writel APIs for this.

If the main clock for a hwmod is of basic clock type, it is illegal to type
cast this to clk_hw_omap and will result in bogus data. Fixed by checking
the clock flags before attempting the type cast.

* [PATCHv9 36/43] ARM: OMAP: hwmod: fix an incorrect clk type cast with _get_clkdm

If the main clock for a hwmod is of basic clock type, it is illegal to type
cast this to clk_hw_omap and will result in bogus data. Fixed by checking
the clock flags before attempting the type cast.

* [PATCHv9 37/43] ARM: OMAP3: hwmod: initialize clkdm from clkdm_name

DT clocks are mostly missing clkdm info now, and this causes an issue with
counter32k which makes its slave idlemode wrong and prevents core idle.
Fixed by initializing the hwmod clkdm pointers for omap3 also which makes
sure the clkdm flag matching logic works properly.
This patch also changes the return value for _init_clkdm to 0 for
incorrect clkdm_name, as this a warning, not a fatal error.

This patch provides top level functionality for the DT clock initialization.
Clock tree is initialized hierarchically starting from IP modules (CM/PRM/PRCM)
going down towards individual clock nodes, and finally initializing
clockdomains once all the clocks are ready.

clk_init is now separated to a common function which gets called for all
SoC:s, which initializes the DT clocks and calls the SoC specific clock init.

* [PATCHv9 39/43] ARM: OMAP2+: io: use new clock init API
@ 2013-10-25 15:57 ` Tero Kristo

From: Tero Kristo @ 2013-10-25 15:57 UTC (permalink / raw)
To: linux-arm-kernel
clk_init is now separated to a common function which gets called for all
SoC:s, which initializes the DT clocks and calls the SoC specific clock init.

OMAP4 clocks have now been moved to DT, thus remove the old data file
and use the new init code under drivers/clk/omap/clk-44xx.c.

* [PATCHv9 40/43] ARM: OMAP4: remove old clock data and link in new clock init code
@ 2013-10-25 15:57 ` Tero Kristo
0 siblings, 0 replies; 212+ messages in thread
From: Tero Kristo @ 2013-10-25 15:57 UTC (permalink / raw)
To: linux-arm-kernel
OMAP4 clocks have now been moved to DT, thus remove the old data file
and use the new init code under drivers/clk/omap/clk-44xx.c.

From: Tero Kristo @ 2013-10-25 15:57 UTC (permalink / raw)
To: linux-arm-kernel
AM33xx clocks have now been moved to DT, thus remove the old data file
and use the new init code under OMAP clock driver.

What is you use case for these clocks with a fixed factor of 1? Wouldn't
it be simpler to just use sys_clkin_ck from the devices?

This is just kind of a dummy clock node for the driver use, so that it
is simpler for them to find their clocks. If these are dropped, the
drivers need to know that instead of their old own mcaspX_fck, they now
need to directly connect to sys_clkin_ck. This also allows to track
usecounts for the clocks better, if you don't have the mcaspX_fck:s for
example, you will just have a usecount of 25 for the sys_clkin_ck, but
don't really know who is using it. Also, other SoCs most likely have the
same name in use, so just to keep the clock data compatible across SoCs.
These files are also completely autogenerated from the existing clock
data under mach-omap2, and these nodes exist there.
But yea, no hard requirement.

This is just kind of a dummy clock node for the driver use, so that it
is simpler for them to find their clocks. If these are dropped, the
drivers need to know that instead of their old own mcaspX_fck, they now
need to directly connect to sys_clkin_ck. This also allows to track
usecounts for the clocks better, if you don't have the mcaspX_fck:s for
example, you will just have a usecount of 25 for the sys_clkin_ck, but
don't really know who is using it. Also, other SoCs most likely have the
same name in use, so just to keep the clock data compatible across SoCs.
These files are also completely autogenerated from the existing clock
data under mach-omap2, and these nodes exist there.
But yea, no hard requirement.

We shouldn't add dummy clocks to simplify debugging, maybe we need some
user tracking in the core clk code?
As there are only few of these factor 1 clocks, I'm fine with keeping
them for consistency here.

Yea might be good to have something like this as configurable option in
the future, so you would know who has enabled a certain clock. Currently
clock APIs don't really provide way to tell users apart from each other.
Mike, any thoughts on this?

I have one question here, what makes this part of the patch
TI-specific at all except the definition of the structure ti_dt_clk?
Mapping DT clocks to generic clkdev legacy namings seems like it would
be a necessary evil across *all* SoC platforms.
I would say there is a good case for this being generic and used by
all platforms waiting for con->id/dev->id to be moved to DT-awareness,
the structure itself is very generic within clkdev as long as the
drivers conformed anyway (and if they didn't, none of this helps) and
I don't think it really needs to be a TI-only thing. The next thing
that's going to happen when another platform arrives that wants to do
the same thing is duplication or consolidation - so it would probably
be a good idea to make this generic to start.
While there the names could be a bit more descriptive -
dt_clk_name_lookup_map_register(), struct dt_clk_name_lookup_map,
DT_CLK_LOOKUP_MAP() ..? The current namespace makes it look like this
is the absolute correct thing to do under all circumstances, but in
fact this is purely for mapping the old way to the new, better way..
in the event a brand new platform arrives, with all new drivers (or
only compliant drivers), none of this code should be implemented for
it and it should be presented this way.

I just sent you a private email with a patch to try out, should fix the
boot crash at least hopefully. Basically I forgot to convert one part of
the kernel to the new regmap stuff for omap36xx.
clkdm issues are caused by wrong data in omap_hwmod_3xxx_data.c, USB
nodes are listing l3_init_clkdm for them, but this only exists on
omap4+. Seems like some copy paste bug introduced by someone.
dpll5 part I am not too sure, can you check if the same happens with
non-dt boot?

Again, I don't think this is related to this series, but rather to
missing/wrong hwmod data.

I just sent you a private email with a patch to try out, should fix the
boot crash at least hopefully. Basically I forgot to convert one part of
the kernel to the new regmap stuff for omap36xx.
clkdm issues are caused by wrong data in omap_hwmod_3xxx_data.c, USB
nodes are listing l3_init_clkdm for them, but this only exists on
omap4+. Seems like some copy paste bug introduced by someone.
dpll5 part I am not too sure, can you check if the same happens with
non-dt boot?

Again, I don't think this is related to this series, but rather to
missing/wrong hwmod data.

An earlier implementation of this patch (or at least a patch that tries
to accomplish the same as this does, add support for legacy devices) did
try to add generic solution. There was some discussion on it and I
decided to drop it due to bad feedback.

Btw, I also noticed the following section mimatches:

the function prcm_probe() to the (unknown reference) .init.data:(unknown)
The function prcm_probe() references

This is often because prcm_probe lacks a __initdata

I don't see anything that says this should not be generic, just that
it was implemented relatively poorly at the time...
I agree with Tomasz, find_by_name in device trees is basically evil
(it's only supposed to be used if you already know the name because
something else passed it to you, and just want it's phandle, but names
CAN be ambiguous. The real fix is always pass phandles and not strings
of the name property), but that's not to say this thing needs to be
TI-specific..
Ah well. If it ends up getting used elsewhere, it can be quickly
patched into a generic version anyway, so.. yay!
I'm really interested in this all going in - but I would love to see
where this is just all patched into a tree already. Pulling things out
against a bunch of trees gave me more merge failures and weird
happenings than I care to deal with. Is there a TI clock development
tree with all this in somewhere publically accessible? I'd like to get
a feel for how the DT looks and what's going on, I can't "see" it from
the patches. Once it's there.. I'll spend a week or 5 doing all of the
i.MX chips and you'll have a second test case for any problems :)

Tracked this down: you were missing the following - looks like the

Tracked this down: you were missing the following - looks like the
conversion script might be missing converting the flags clock data
over to dts?

Yea, seems I introduced the problem with the conversion script changes.
The valid fix for this is actually at the end of this mail (this fixes
both of the problems introduced, and also completes the fix you did), I
will add the fixes to the next rev. Question to Mike/Paul/Tony/Benoit,
shall I resend the complete series or only the two patches that will be
changed?

Yeah, this can be converted to generic version easily if need be. The
thing with this patch is also that it is kind of temporary solution, it
should not be needed anymore once all the drivers are converted to DT.

Did you try the fully integrated test tree I mentioned in the cover letter?
tree: https://github.com/t-kristo/linux-pm.git
branch: 3.12-rc6-dt-clks-v9
This has everything in it, and compiles cleanly.

One debug feedback:
reg = <0x0d04>, <0x0d24>, <0x0d34>, <0x0d4c>;
clocks = <&sys_ck>, <&sys_ck>;
we used indexing for varied register and clocks. however the register
meaning per index changes based on type of DPLL. This was one painful
thing to track down when debugging. the only robust option to debug
was to use prints as part of register write/reads to ensure that right
sequence was being followed.
I understand based on review comments for dtb size, we have removed
the names, but we lost sane debug capability as well with that.

One debug feedback:
reg = <0x0d04>, <0x0d24>, <0x0d34>, <0x0d4c>;
clocks = <&sys_ck>, <&sys_ck>;
we used indexing for varied register and clocks. however the register
meaning per index changes based on type of DPLL. This was one painful
thing to track down when debugging. the only robust option to debug
was to use prints as part of register write/reads to ensure that right
sequence was being followed.
I understand based on review comments for dtb size, we have removed
the names, but we lost sane debug capability as well with that.

Might it not be better to introduce regmap variants?
static inline void clk_regmap_writel(u32 val, u32 reg, struct regmap
*regmap)
and corresponding readl? that allows cleaner readability for clk
drivers that use regmap and those that dont.
regmap can also return error value that could also be handled as a result.

If we move mult-div1 above autoidle, indices for control, idlest,
mult-div1 will be constant with DPLLs that dont have autoidle. a
little easier to debug.

There is no if checks for DPLL_LOCKED which is set with ti,lock,
should we just drop it?

Well, doing that will introduce a lot of redundant code, as the checks
for the presence of regmap must be copied all over the place. With this
patch, all the generic clock drivers support internally both regmap or
non-regmap register accesses.

True, however if the regmap fails for the clock code, not sure what we
can do but panic. If this code is expanded, it is probably better to not
inline it anymore.

Probably better to keep it in, as there might be some code in future
which needs this. Kind of better for readability also, as the field is
specified to list the valid modes for the DPLL. One could argue that
current kernel code is wrong for _omap3_dpll_write_clken(clk,
DPLL_LOCKED) as it does not check if the mode is valid for the DPLL or not.

Oh it does? Never seen that happen as kzalloc never failed for me. :)
However, I can remove these as I don't think they will ever happen anyway.

Eventually yes. Currently it fails to compile if you do OMAP4 / OMAP5
only build, as you don't have the OMAP3 support routines in.

Eventually yes. Currently it fails to compile if you do OMAP4 / OMAP5

I must admit I am confused here.
a) of_clk_init (in the generic clk.c) uses of_clk_init_cb_t as match
data. The prototype of the generic of_clk_init_cb_t is typedef void
(*of_clk_init_cb_t)(struct device_node *);
b) both of_clk_init and ti_dt_clk_init_provider looks up clock nodes
from __clk_of_table
I assume we need ti_dt_clk_init_provider to be always called with
clock list, as a result of_clk_init(NULL); will never be invoked. This
is counter productive as you have have generic non SoC clock providers
as well who would have been invoked with of_clk_init(NULL);
I do strongly encourage using of_clk_init(NULL) and not having to
switch the clk_init call back with SoC specific one as it forces
un-intended dependency.
Further such as SoC specific callback should have been in a header.

one further comment - using pr_fmt will save us from using __func__
for every pr_* message :(

let the compiler deal with that decision. regmap operation fail should
be percollated back to initiator of the request. in some cases that
will be ir-recoverable, but on other cases panic might be the right
answer - at the low level we are in no position to make that distinction.

you could move the for loop in the else case and reduce the loops to
CLK_COMPONENT_TYPE_MUX+1 to CLK_COMPONENT_TYPE_MAX.

could you not just do a kfree(clks[i]) and set the component_clks to NULL?
Further, if there are only 3 clocks that can ever be present and we do
not allow for duplicates types, could we not do those checks in
ti_clk_add_component instead of having a harder recovery in setup of
composite clk?

makes sense only if ti,dividers are not defined, right?
CLK_DIVIDER_ONE_BASED is used with !table

CLK_DIVIDER_POWER_OF_TWO is used with !table

These are part of auto idle driver bindings, so maybe give a link to that?

yeah - this is one of those properties that should probably become
generic at a later point in time.

an example of ti,dividers will be useful as well.

alright, this does not really map back to ti,divder-clock style
handling.. aren't they supposed to be consistent?
how about "ti,index-power-of-two", bit shift etc?

makes sense only if ti,dividers are not defined, right?
CLK_DIVIDER_ONE_BASED is used with !table

CLK_DIVIDER_POWER_OF_TWO is used with !table

These are part of auto idle driver bindings, so maybe give a link to that?

yeah - this is one of those properties that should probably become
generic at a later point in time.

an example of ti,dividers will be useful as well.

will be nice to get warning if ti,divider is defined and any of the

if this fails, table will be freed though, we have added provider and

alright, this does not really map back to ti,divder-clock style
handling.. aren't they supposed to be consistent?
how about "ti,index-power-of-two", bit shift etc?

The above three belong to autoidle stuff I think.. maybe pointing to

Initial work I did for v9 had clk_reg_ops struct in place which pretty
much did this, however Mike recommended looking at the regmap so I did.
I could put the reg_ops struct back and just have it use internally
regmap if that would be better, but I guess we need comment from Mike
how he wants this to be done.
We could have:
struct clk_reg_ops {
int (*clk_readl)(u32 addr, u32 *val);
int (*clk_writel)(u32 addr, u32 val);
};
struct clk_foo {
...
void __iomem *reg;
struct clk_reg_ops *regops;
};

Currently, none of the clock drivers handle failures for regmap
operations, I can of course add some sort of support for this given what
we do with above point and what the API for the register accesses ends
up like.

__clk_of_table contains the function pointers for the clock init
functions, not clock nodes.

Can't call of_clk_init(NULL) anymore, as Paul wants to map the clock
nodes under respective IP blocks. Two reasons here:
a) This requires me to pass some info from the IP block (CM1/CM2/PRM) to
the clock init functions, basically the pointer to the memory map region
(regmap.)
b) of_clk_init(NULL) will initialize all the clock nodes in the system,
irrespective of the hierarchy considerations.
Only thing that can be done, is to make the API introduced in this patch
a generic API and call it something like of_clk_init_children().

You get zero offset.

What do you propose to do in error case? Panic, WARN() or just printk?

The list is shared between all composite clocks, as we don't have
knowledge into which clock each component will go to at the time of the
component registration. Consider this setup (comp = component):
comp-a1
comp-a2
composite-a : comp-a1 + comp-a2
comp-b1
comp-b2
comp-b3
composite-b : comp-b1 + comp-b2 + comp-b3
Depending on clock init order, we will potentially have 5 components in
the list at max, which of 2 + 2 are of same type.

Yea can add a enum for that, good for the rest of the points listed for

The list is shared between all composite clocks, as we don't have
knowledge into which clock each component will go to at the time of the
component registration. Consider this setup (comp = component):
comp-a1
comp-a2
composite-a : comp-a1 + comp-a2
comp-b1
comp-b2
comp-b3
composite-b : comp-b1 + comp-b2 + comp-b3
Depending on clock init order, we will potentially have 5 components in
the list at max, which of 2 + 2 are of same type.

Well I was considering this, however this would require extra level of
registration also:
of_ti_composite_clk_setup ->
(match children against composite types)
of_ti_composite_divider_setup
of_ti_composite_gate_setup
Might be cleaner overall though, so I can take a look at this.

Well I was considering this, however this would require extra level of
registration also:
of_ti_composite_clk_setup ->
(match children against composite types)
of_ti_composite_divider_setup
of_ti_composite_gate_setup
Might be cleaner overall though, so I can take a look at this.

Provider and regmap are shared for the whole IP block (CM/PRM whatever.)

Unregister is not supported currently. I don't think I want to do
partial cleanup here, failing autoidle setup is not critical anyway. The
system will still boot-up properly, only PM is potentially broken. Can
add an error print though.

Some minor confusion here in my comment, sorry about that.
Regmap is shared for the whole IP block and initialized only once, we
can't remove it here as it is not owned by this clock. For
clock-provider / unregister part, I don't want to clean those up as 1)
unregister doesn't currently do anything 2) autoidle setup is not
critical failure, it just breaks PM. I can add error print for it though.

yes, apologies, should have stated the prototypes of functions in a
single __clk_of_table should not be two different argument list. The
reason is as follows: CLK_OF_DECLARE fills up that list. there can be
generic drivers such as [1] which might be registered, OR in the case
of MULTI_ARCH - multiple other SoC drivers would have registered
there. There is a bunch of stuff we could mess up here.
If we do not have a choice, if we would like to maintain a different
prototype based init list, we should probably do it in a different
structure - example __clk_of_table_regmap or something similar..

you still can do that:
of_prcm_init->ti_dt_clk_init_provider-> instead of matching nodes from
__clk_of_table, you can make it __clk_of_regmap_table -> the
CLK_OF_DECLARE will not be good enough here ofcourse, but this will
probably belong to a generic regmap enabled clock support framework -
i dont see much that is TI specific in drivers/clk/ti/clk.c and it
makes sense to be part of generic clock framework handling as generic
clock framework will receive regmap support based on previous patches.
that allows for other platforms to use regmap based clk drivers as well.

return error to caller and percolate back up the call stack.
one other thing I missed, will be nice to introduce a common bindings
for autoidle which tends to be reused in other drivers..

Would IP blocks driven by clocks work with the autoidle configuration
broken? I believe we will be writing to DPLL_XYZ_GATE_CTRL? the usage
I believe is around
of_ti_clk_deny_autoidle_all/of_ti_clk_allow_autoidle_all which gets
invoked in omap2_clk_disable_autoidle_all part of xyz SoC init call.
is'nt the reason we do that to ensure we have no potential race when
clocks dissapear on their own without explicit control in critical
configuration paths?

i think you may want to sequence patch #12 before this if you would

an example will be nice for this.

eventually, this can disappear ofcourse.. and that will pave way to
remove the clock domain data to dts as well.. but yes, we have to find
a proper home for this away from current location..

since we are using of_clk_get, it will be good to provide
documentation w.r.t when the call is expected to be invoked.

mandatory parameter without check?
ti,index-starts-at-one, ti,set-rate-parent
these seem not supported here even though the bindings dont tell us that.

I dont have any further feedback at this point beyond what is already
shared and so far my minimal tests have been good..
I have the following warnings:
sparse build warnings: http://pastebin.com/HZ1TWzyh
kernel-doc warnings: http://pastebin.com/JQwFEuaC
Hopefully, the next rev will not introducing nothing newer that what
we have in mainline.

The idea itself sounds not bad, but patch description fails to specify
what is the need for this. I mean, if you know that this will have some
actual users, it is nice to specify them.
Also IMHO the variant with clk_reg_ops (but with regmap used) would look a
bit better in terms of readability and extensibility, but I'm leaving this
completely to Mike's decision.
(OR maybe you could migrate this fully to regmap, which can do MMIO
accesses as well, without the need of having separate code paths for both
in clock code?)
Best regards,
Tomasz

SoC platforms that are fully converted to Device Tree do not need any
legacy clkdev namings, because they have all clkdev look-ups performed
using data from DT (see generic clock bindings).
So this would be not "*all* SoC platforms", but instead "SoC platforms,
which are currently undergoing conversion to DT or conversion of which is
yet to be started".
Still this might be a good enough justification for having a generic
solution for this problem, but I would wait with this until the real need
on some of such platforms shows up. I don't see anything wrong in
implementing this first as TI-specific quirk and then possibly making it
generic if such need shows up.
By the way, we already have something like this in clk/samsung/clk.c .
This is called aliases there and allows registering clkdev look-ups for
particular clocks. However this is specific to our clock drivers that
register all clocks inside a single clock privder, based on static ID
assignment and all clocks statically listed in clock driver - see
clk/samsung/clk-s3c64xx.c for an example.

Tomasz

I will have a look at those for the next rev, will most likely post next
against 3.13-rc1, there's no much point posting before.

Yea different init tables can be introduced, however I still need to
split the support between hierarchical version and the blunt version
that registers everything. Looking at the work from Jyri, its possible I
need to add calls to both.

You mean documentation or? Autoidle from this patch is only used by two
clock drivers (divider + fixed-factor.) DPLLs use completely different
setup. Converting the interface clocks to use the same might be rather
nasty thing to do.

Could do that with some links yea, similar to how the clock data mods
are done in this rev. Will check it out how it works.

The definitions are common - so, yes, it will be nice to have
autoidle.txt which is then pointed to by divider, fixed-clock etc..

That is well understood here, I have a long-running hobby project to
do this for i.MX5 and i.MX6 - I have a tree from months ago where I
restructured the way clocks are probed for both these (moving from
mach-imx to drivers/clk and putting in the right places) and
successfully moved 8 clocks (on i.MX51, 3 core PLLs, some fixed clocks
which got done in the meantime upstream, and one in the CCM - the CPU
freq divider) with the correct references and it all operated really
well.
In the meantime I had to add a bunch of weird hacks to the drivers to
deal with the missing connection names, so this being generic would
allow the core clock work to be finished while the drivers are brought
up to the new convention.

Indeed.. and I would like to make use of it but I'm not coding on a TI
platform or a Samsung platform:)

Right. I'll keep it in mind as I do this.
Thanks, this does make my life a lot easier, means I might have it
working and submitted before the end of the month instead of sometime
next year, I was dreading reworking all these drivers up front ;)

Well, it might be good for debugging if someone forgets the shift when
he was supposed to add one. I could also make this a required property,
but this will increase the dtb size slightly, there are quite a few
mux-clocks around with 0 bit-shift atm.

Yes. Currently this is the case at least, but we can add more beef to
the binding to handle holes if this comes up in future. Or alternatively
just add dummy-ck as mux parent and cover the holes that way.

I was thinking about using it, however this will allow us to route
everything to their individual driver APIs. Anyway, I guess that is
rather moot point so I will look at this again.

Please keep in mind that the "identity" of clk_readl() and
readl() only applies in the current source code (ARM only use of
common CCF primitives), while patches are pending (currently
under review and receiving further improvement) which introduce
several alternative implementations of clk_readl() depending on
the platform. Making all of them duplicate the "regmap vs direct
register access" branch would be as bad. Keeping one set of
clk_readl() and clk_writel() routines and adding #ifdefs around
the direct register access would be rather ugly, and I understand
that preprocessor ifdef counts should get reduced instead of
introduced.

So, it might be better to provide platform / or clock specific
clk_reg_ops or something, so we can cover all the possible cases easily.
The requirement from TI SoC point of view is that:
1) need to be able to specify custom register read/write ops
2) need to be able to provide an index parameter to the read/write ops
3) need to be able to provide a register offset to the read/write ops
This could be done in following way for example:
clk_readl / clk_writel would be accessed through a single platform
specific struct which provides function pointers to both.
The content of 'reg' provided to the clk_readl / clk_writel would be
internally interpreted as a
struct omap_clk_reg_internal {
u16 offset;
u16 index;
};
... the index part would be used to select the appropriate regmap to
use, and TI SoC:s would be using 3...4 regmaps for actually accessing
the physical registers themselves.
