Hi,
This set mainly fixes comments received from Nishanth Menon for v4.
AM43xx + AM35xx clock data was added as new feature, also OMAP3
platforms use either the old style kernel clock data or DT data,
based on boot type.
Testing done:
omap3 beagle : boot, suspend / resume
omap4 panda es: boot, suspend / resume
omap5 sevm: boot
am335x bone: boot
Branch available here:
git://gitorious.org/~kristo/omap-pm/omap-pm-work.git
branch: mainline-3.11-rc3-omap-dt-clks-v5

clk_get_sys / clk_get can now find clocks from device-tree. If a DT clock
is found, an entry is added to the clk_lookup list also for subsequent
searches.

+Binding for Texas Instruments DPLL clock.
+
+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,omap4-dpll-x2-clock",
+ "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-core-clock",
+ "ti,omap4-dpll-m4xen-clock",
+ "ti,omap4-dpll-j-type-clock",
+ "ti,omap4-dpll-no-gate-clock",
+ "ti,omap4-dpll-no-gate-j-type-clock",
+
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks (clk-ref and clk-bypass)
+- reg : array of register base addresses for controlling the DPLL (some
+ of these can also be left as NULL):
+ reg[0] = control register
+ reg[1] = idle status register
+ reg[2] = autoidle register
+ reg[3] = multiplier / divider set register
+- ti,clk-ref : link phandle for the reference clock
+- ti,clk-bypass : link phandle for the bypass clock
+
+Optional properties:
+- ti,modes : available modes for the DPLL
+- ti,recal-en-bit : recalibration enable bit
+- ti,recal-st-bit : recalibration status bit
+- ti,auto-recal-bit : auto recalibration enable bit
+- ti,clkdm-name : clockdomain name for the DPLL
+
+Examples:
+ dpll_core_ck: dpll_core_ck@44e00490 {
+ #clock-cells = <0>;
+ compatible = "ti,omap4-dpll-core-clock";
+ clocks = <&sys_clkin_ck>;

+ <0x44e00468 0x4>;
+ ti,clk-ref = <&sys_clkin_ck>;
+ ti,clk-bypass = <&sys_clkin_ck>;
+ };
+
+ dpll2_ck: dpll2_ck@48004004 {

From: Tero Kristo @ 2013-08-02 16:25 UTC (permalink / raw)
To: linux-arm-kernel
The OMAP clock driver now supports DPLL clock type. This patch also
adds support for DT DPLL nodes.

+Binding for Texas Instruments DPLL clock.
+
+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,omap4-dpll-x2-clock",
+ "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-core-clock",
+ "ti,omap4-dpll-m4xen-clock",
+ "ti,omap4-dpll-j-type-clock",
+ "ti,omap4-dpll-no-gate-clock",
+ "ti,omap4-dpll-no-gate-j-type-clock",
+
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks (clk-ref and clk-bypass)
+- reg : array of register base addresses for controlling the DPLL (some
+ of these can also be left as NULL):
+ reg[0] = control register
+ reg[1] = idle status register
+ reg[2] = autoidle register
+ reg[3] = multiplier / divider set register
+- ti,clk-ref : link phandle for the reference clock
+- ti,clk-bypass : link phandle for the bypass clock
+
+Optional properties:
+- ti,modes : available modes for the DPLL
+- ti,recal-en-bit : recalibration enable bit
+- ti,recal-st-bit : recalibration status bit
+- ti,auto-recal-bit : auto recalibration enable bit
+- ti,clkdm-name : clockdomain name for the DPLL
+
+Examples:
+ dpll_core_ck: dpll_core_ck at 44e00490 {
+ #clock-cells = <0>;
+ compatible = "ti,omap4-dpll-core-clock";
+ clocks = <&sys_clkin_ck>;
+ reg = <0x44e00490 0x4>, <0x44e0045c 0x4>, <0x0 0x4>,
+ <0x44e00468 0x4>;
+ ti,clk-ref = <&sys_clkin_ck>;
+ ti,clk-bypass = <&sys_clkin_ck>;
+ };
+
+ dpll2_ck: dpll2_ck at 48004004 {
+ #clock-cells = <0>;
+ compatible = "ti,omap3-dpll-clock";
+ clocks = <&sys_ck>;
+ ti,modes = <0xa2>;
+ ti,clk-bypass = <&dpll2_fck>;
+ reg = <0x48004004 0x4>, <0x48004024 0x4>, <0x48004034 0x4>,
+ <0x48004040 0x4>;
+ ti,clkdm-name = "dpll2_clkdm";
+ ti,clk-ref = <&sys_ck>;
+ ti,recal-en-bit = <0x8>;
+ ti,auto-recal-bit = <0x3>;

* [PATCHv5 03/31] CLK: TI: add DT alias clock registration mechanism

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.

* [PATCHv5 03/31] CLK: TI: add DT alias clock registration mechanism

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.

+This binding uses the common clock binding[1]. Autoidle clocks

+fixed-factor-clock [3] and just add autoidle support on top of
+this. Autoidle is an OMAP clock feature, which allows the clock
+to gate autonomously by hardware when they are no longer needed.
+The autoidle feature must be enabled manually for these clocks.

+Binding for Texas Instruments gate clock.
+
+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
+
+Required properties:
+- compatible : shall be "ti,gate-clock"
+- #clock-cells : from common clock binding; shall be set to 0
+- clocks : link to phandle of parent clock
+
+Optional properties:
+- reg : base address for register controlling adjustable gate
+- ti,enable-bit : bit shift for programming the clock gate
+- ti,dss-clk : use DSS hardware OPS for the clock
+- ti,am35xx-clk : use AM35xx hardware OPS for the clock
+- ti,clkdm-name : clockdomain to control this gate
+
+Examples:
+ trace_clk_div_ck: trace_clk_div_ck {
+ #clock-cells = <0>;
+ compatible = "ti,gate-clock";
+ clocks = <&trace_clk_div_div_ck>;
+ ti,clkdm-name = "emu_sys_clkdm";
+ };
+
+ emac_ick: emac_ick@4800259c {

+ compatible = "ti,gate-clock";
+ clocks = <&ipss_ick>;
+ reg = <0x4800259c 0x4>;
+ ti,clkdm-name = "core_l3_clkdm";
+ ti,enable-bit = <1>;
+ ti,am35xx-clk;

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.

* [PATCHv5 06/31] ARM: dts: omap4 clock data
@ 2013-08-02 16:25 ` Tero Kristo

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.

* [PATCHv5 08/31] ARM: OMAP4: remove old clock data and link in new clock init code
@ 2013-08-02 16:25 ` Tero Kristo

From: Tero Kristo @ 2013-08-02 16:25 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.

* [PATCHv5 12/31] ARM: dts: dra7 clock 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.

* [PATCHv5 12/31] ARM: dts: dra7 clock data
@ 2013-08-02 16:25 ` 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.

From: 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.
+
+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 : array of register base addresses for controlling the APLL:
+ reg[0] = control register
+ reg[1] = idle status register
+- ti,clk-ref : link phandle for the reference clock
+- ti,clk-bypass : link phandle for the bypass clock
+
+Examples:
+ apll_pcie_ck: apll_pcie_ck@4a008200 {
+ #clock-cells = <0>;
+ clocks = <&apll_pcie_in_clk_mux>;

* [PATCHv5 16/31] CLK: TI: DRA7: Add APLL support
@ 2013-08-02 16:25 ` Tero Kristo

To: linux-arm-kernel
From: 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.
+
+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 : array of register base addresses for controlling the APLL:
+ reg[0] = control register
+ reg[1] = idle status register
+- ti,clk-ref : link phandle for the reference clock
+- ti,clk-bypass : link phandle for the bypass clock
+
+Examples:
+ apll_pcie_ck: apll_pcie_ck at 4a008200 {
+ #clock-cells = <0>;
+ clocks = <&apll_pcie_in_clk_mux>;
+ reg = <0x4a00821c 0x4>, <0x4a008220 0x4>;
+ ti,clk-bypass = <&dpll_pcie_ref_ck>;
+ ti,clk-ref = <&apll_pcie_in_clk_mux>;
+ compatible = "ti,dra7-apll-clock";
+ };

* [PATCHv5 20/31] CLK: TI: add am33xx clock init file

To: linux-omap, paul, tony, nm, rnayak, mturquette
Cc: linux-arm-kernel, devicetree
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.

* [PATCHv5 20/31] CLK: TI: add am33xx clock init file

To: linux-arm-kernel
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.

* [PATCHv5 21/31] ARM: AM33xx: remove old clock data and link in new clock init code
@ 2013-08-02 16:25 ` Tero Kristo

From: Tero Kristo @ 2013-08-02 16:25 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.

Cc: linux-arm-kernel, devicetree
OMAP3 has interface clocks in addition to functional clocks, which
require special handling for the autoidle and idle status register
offsets mainly.

+Binding for Texas Instruments interface clock.
+
+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 "ti,interface-clock"
+- #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,enable-bit : bit shift for the bit enabling/disabling the clock
+ (default 0)
+- ti,iclk-no-wait : flag for selecting non-waiting hw-ops
+- ti,iclk-hsotgusb : flag for selecting hsotgusb hw-ops
+- ti,iclk-dss : flag for selecting DSS interface clock hw-ops
+- ti,iclk-ssi : flag for selecting SSI interface clock hw-ops
+- ti,am35xx-clk : flag for selecting AM35xx interface clock hw-ops
+- ti,clkdm-name : parent clockdomain name
+
+Examples:
+ aes1_ick: aes1_ick@48004a14 {
+ #clock-cells = <0>;
+ compatible = "ti,interface-clock";
+ clocks = <&security_l4_ick2>;
+ reg = <0x48004a14 0x4>;
+ ti,enable-bit = <3>;
+ };
+
+ cam_ick: cam_ick@48004f10 {
+ #clock-cells = <0>;
+ compatible = "ti,interface-clock";
+ clocks = <&l4_ick>;
+ reg = <0x48004f10 0x4>;
+ ti,clkdm-name = "cam_clkdm";
+ ti,enable-bit = <0>;
+ ti,iclk-no-wait;

* [PATCHv5 22/31] CLK: TI: add interface clock support for OMAP3

To: linux-arm-kernel
OMAP3 has interface clocks in addition to functional clocks, which
require special handling for the autoidle and idle status register
offsets mainly.

+Binding for Texas Instruments interface clock.
+
+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 "ti,interface-clock"
+- #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,enable-bit : bit shift for the bit enabling/disabling the clock
+ (default 0)
+- ti,iclk-no-wait : flag for selecting non-waiting hw-ops
+- ti,iclk-hsotgusb : flag for selecting hsotgusb hw-ops
+- ti,iclk-dss : flag for selecting DSS interface clock hw-ops
+- ti,iclk-ssi : flag for selecting SSI interface clock hw-ops
+- ti,am35xx-clk : flag for selecting AM35xx interface clock hw-ops
+- ti,clkdm-name : parent clockdomain name
+
+Examples:
+ aes1_ick: aes1_ick at 48004a14 {
+ #clock-cells = <0>;
+ compatible = "ti,interface-clock";
+ clocks = <&security_l4_ick2>;
+ reg = <0x48004a14 0x4>;
+ ti,enable-bit = <3>;
+ };
+
+ cam_ick: cam_ick at 48004f10 {
+ #clock-cells = <0>;
+ compatible = "ti,interface-clock";
+ clocks = <&l4_ick>;
+ reg = <0x48004f10 0x4>;
+ ti,clkdm-name = "cam_clkdm";
+ ti,enable-bit = <0>;
+ ti,iclk-no-wait;

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.

* [PATCHv5 25/31] 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.

* [PATCHv5 28/31] ARM: dts: AM35xx clock data
2013-08-02 16:25 ` Tero Kristo

From: Tero Kristo @ 2013-08-02 16:25 UTC (permalink / raw)
To: linux-omap, paul, tony, nm, rnayak, mturquette
Cc: linux-arm-kernel, devicetree
This patch creates a unique node for each AM35xx specific clock in the
AM35xx power, reset and clock manager (PRCM). Most of the AM35xx clock
data is shared with OMAP3xxx, this patch only creates the delta.

* [PATCHv5 28/31] ARM: dts: AM35xx clock data
@ 2013-08-02 16:25 ` Tero Kristo

To: linux-arm-kernel
This patch creates a unique node for each AM35xx specific clock in the
AM35xx power, reset and clock manager (PRCM). Most of the AM35xx clock
data is shared with OMAP3xxx, this patch only creates the delta.

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.

Why are we introducing the "lookup by name" brokenness to the yet (mostly)
sane DT world?
We already have a good way of binding things together in DT, which is
using phandles.
Not even saying that this (or something this patch relies on) breaks the
ePAPR recommendation about node naming, which states that node names
should not be used to convey platform-specific data, but instead should be
as generic as possible to show what kind of hardware is represented by the
node.
Best regards,
Tomasz
P.S. Added missing DT maintainers to CC.

Hmm, why do you need to pass references to other clocks using private
properties? Is there a reason you can't use the clocks and clock-names
properties defined by standard clock bindings?
The same for other PLLs defined in this patch.

Hmm, why do you need to pass references to other clocks using private
properties? Is there a reason you can't use the clocks and clock-names
properties defined by standard clock bindings?
The same for other PLLs defined in this patch.

This is utterly broken if you're looking up purely by a connection ID.
Please, go back and read clk_get()'s documentation in linux/clk.h.
It's spelt out very plainly there.
NAK.

Tell me this: many devices name their clock inputs. You can find these
input names in data sheets and the like. These are the names defined
by the hardware. What is wrong about using those names in DT?
Remember that the second argument to clk_get() is the _clock_ _input_
_name_ on the _device_ passed in the first argument. It is not *ever*
some random name of the clock producer unless someone's fscked up their
use of this API (in which case they're the ones with the problem.)

Yes, clock inputs. But this is about lookup by clock name, not clock input
name, as far as I can tell from the patch, based on looking for a node
with given name over the whole DT.

This is perfectly fine and this is how the generic common clock framework
DT bindings work - clock-names property is a list of clock input names and
clocks property contain specifiers of respective clocks.

"con_id" is supposed to be the clock input name when the clock API is
used correctly.

There seems to be a some pressure to do clk_get()->of_clk_get()
conversions, and also to find ways to lookup clocks. It seems to me
that no one understands how DT handles clocks. Maybe that's where the
problem is - lack of documentation about how DT clocks are handled.

Right. Still, the code is looking for a node with the same name as the
supposed input name, which seems strange to me, because clock input names
are supposed to be defined in consumer's node, inside clock-names
property.

I don't really see any need for this kind of conversion. clk_get() already
handles lookup using DT correctly and from drivers perspective nothing
changes.

Hmm, there is pretty much of description and examples in
Documentation/devicetree/bindings/clock/clock-bindings.txt
For me it was enough to learn how DT based clock lookup works, but I'm
quite used to DT, so I'm not a good test sample.

Maybe try to have a generic init function, then have SoC specific
quirk function pointers set up based on the DT compatible property?
Grep for varioius _of_match[] examples in the drivers.
That way you might be able to make clocks work for some new similar
hardware with just .dts change and patching in the quirks later on
as needed ;)

It might be a good idea to use clock-names to clarify which clocks are
present (I notice your examples contain only one clock input).

Are all of these always present? Using reg-names seems sensible here.

You already have these in clocks, why do you need them again here?

Huh? What type is that property? What does it mean?

These seem rather low-level, but I see other clock bindings are doing
similar things. When are these needed, and why? What type are they?

Could you elaborate on what this is for? What constitutes a valid name?
I'm not sure a string is the best way to define the linkage of several
elements to a domain...

NAK. Use reg-names to handle registers being optional.

You can get these from the standard clocks property. Don't do this.
Look at of_clk_get_by_name().

It might be a good idea to use clock-names to clarify which clocks are
present (I notice your examples contain only one clock input).

Are all of these always present? Using reg-names seems sensible here.

You already have these in clocks, why do you need them again here?

Huh? What type is that property? What does it mean?

These seem rather low-level, but I see other clock bindings are doing
similar things. When are these needed, and why? What type are they?
> +- ti,clkdm-name : clockdomain name for the DPLL
Could you elaborate on what this is for? What constitutes a valid name?
I'm not sure a string is the best way to define the linkage of several
elements to a domain...

Huh? Why aren't these both in the clocks property?

NAK. Use reg-names to handle registers being optional.

You can get these from the standard clocks property. Don't do this.
Look at of_clk_get_by_name().

Optional? That's odd. If I have a clock with registers, but don't
specify the register, will it still work? i.e. are registerless clocks
really compatible with clocks with registers?.

Why is this needed? Does the hardware vary wildly, or are several clocks
sharing the same register(s)?

Those last two sounds like the kind of thing that should be derived from
the compatible string (e.g. ti,am35xx-gate-clock).

As previously mentioned, I'm not a fan of this property. It would make
more sense to describe the domain and have an explicit link to it
(either nodes being children of the domain or having a phandle).

If they're truly compatible, you can just see if you can of_iomap, and
if not, continue. Your reg values might be wider than 32 bits, and usig
of_property_read_u32 to read this feels wrong.

What if of_property_read_u32 failed to read the "ti,enable-bit"
property? One might not be present, it's marked as optional in the
binding description.

I really don't like this. I think this should be done based on the
compatible string.

Use clocks, clock-names, and of_clk_get_by_name().

Why do you need this?
Is this a description of the hardware, or configuration for Linux?
It feels like the latter, which shouldn't really be in DT.
I'm not that familiar with the internals of the clock framework, and
don't understand the implications of this.
If this is necessary, the bindings need to be updated.
Mike, thoughts?

I think these should be selected based on the compatible string. They're
mutually exclusive, and incompatible.

I think based on these comments this patch needs to go away, I will have
to find another way to map the devices in and to avoid supporting the
legacy mappings (hwmod depends on this heavily atm, but Rajendra posted
some patches to address this.) I'll see what I can do for next rev. I

I think based on these comments this patch needs to go away, I will have
to find another way to map the devices in and to avoid supporting the
legacy mappings (hwmod depends on this heavily atm, but Rajendra posted
some patches to address this.) I'll see what I can do for next rev. I
might implement some tweak inside the OMAP codebase for this.

All DPLLs have both bypass and reference clocks, but these can be the
same. Is it better to just list both always (and hence drop
clock-names), or provide clock-names always?

Not always, I'll change the code. I am quite new to DT and didn't

Bit shift values for the auto recalibration feature. HOWEVER, it seems
these are actually legacy, kernel does not have support for these
anymore if it ever had.... I think I can just drop these for now as they
are unused by the support code even.

Well, I am not sure if we can do this any better at this point, we don't
have DT nodes for clockdomain at the moment (I am not sure if we will
have those either as there are only a handful of those per SoC) but I'll
add some more documentation for this.

I think I implemented this in somewhat confusing manner. This could be
split to:
ti,gate-clock:
requires reg and ti,enable-bit info
ti,clkdm-clock:
requires ti,clkdm-name
clkdm clock is kind of a master clock for clockdomain, the clock is
provided always if the clockdomain is active.

I think I implemented this in somewhat confusing manner. This could be
split to:
ti,gate-clock:
requires reg and ti,enable-bit info
ti,clkdm-clock:
requires ti,clkdm-name
clkdm clock is kind of a master clock for clockdomain, the clock is
provided always if the clockdomain is active.

Yea, same register is shared.

Hmm yea, I think I can change this and add some sub-types.

Same comments as with patch #2.

I'll split this to two separate supported types.

I'll make sure this is present in case it is needed.

Will be changed for next rev, clk-bypass / clk-ref will be populated

I'll see what can be done for this once I figure out what to do with the

Hmm not sure, Keerthy, do you have any comment on this as the patch was

Same, Keerthy? Probably just legacy copy paste from omap2 code and can
be updated based on your comment. Some of these might actually be some
old optimizations, but the APLL enable/disable should be called so
seldom it shouldn't matter. If no objections, I'll just change these all
for next rev.

Hmm not sure, Keerthy, do you have any comment on this as the patch was

Same, Keerthy? Probably just legacy copy paste from omap2 code and can
be updated based on your comment. Some of these might actually be some
old optimizations, but the APLL enable/disable should be called so
seldom it shouldn't matter. If no objections, I'll just change these all
for next rev.

If they're separate inputs, it's worth listing both (even if they're fed
by the same provider). If it's possible one input might not be wired up,
use clock-names.

I'll have to see the documentation, but I'd be very wary of putting that
in as-is. Does having the clock domain string link this up to domains in
platform data?
I'm not sure how well we'll be able to maintain support for that in
future if it requires other platform code to use now, and we're not sure
how the domains themselves will be represented in dt.

Ok. Are those gate clocks are part of a larger "gate clocks" block, with
the register that controls them? or are they really independent? Does
the register control other items too?
If they were part of some bigger unit, it might be possible to have a
binding like the following (though maybe not):
gate_clks: gate_clks {
compatible = "ti,gate-clocks-block";
reg = <0x4003a000 0x1000>;
#clock-cells = <1>;
/*
* has 4 gate clocks at bit shifts 0,1,2,3,
* corresponding to input clocks 0,1,2,3
*/
clocks = <&clk1 0 23>,
<&clk1 0 4>,
<&clk3 2>,
<&clk3 5>;
};
device {
compatible = "vendor,some-device";
clocks = <&gate_clks 1>; /* gate clock with bitshift 1*/
};

Not really. Typically they only have the clockdomain in common, and the
individual clocks are mostly controlled independently from each other.
For example on omap3 we have following register:
CM_FCLKEN_PER
Physical Address 0x4800 5000
BIT31:19 RESERVED Write 0s for future compatibility. Read returns 0.
BIT18 EN_UART4 UART4 functional clock control.
BIT17 EN_GPIO6 GPIO6 functional clock control.
BIT16 EN_GPIO5 GPIO5 functional clock control.
BIT15 EN_GPIO4 GPIO4 functional clock control.
BIT14 EN_GPIO3 GPIO3 functional clock control.
BIT13 EN_GPIO2 GPIO2 functional clock control.
BIT12 EN_WDT3 WDT3 functional clock control.
BIT11 EN_UART3 Type UART3 functional clock control.
BIT10 EN_GPT9 GPTIMER 9 functional clock control.
BIT9 EN_GPT8 GPTIMER 8 functional clock control.
BIT8 EN_GPT7 GPTIMER 7 functional clock control.
BIT7 EN_GPT6 GPTIMER 6 functional clock control.
BIT6 EN_GPT5 GPTIMER 5 functional clock control.
BIT5 EN_GPT4 GPTIMER 4 functional clock control.
BIT4 EN_GPT3GPTIMER 3 functional clock control.
BIT3 EN_GPT2 GPTIMER 2 functional clock control.
BIT2 EN_MCBSP4 McBSP 4 functional clock control.
BIT1 EN_MCBSP3 McBSP3 functional clock control.
BIT0 EN_MCBSP2 McBSP 2 functional clock control.
So multiple drivers will be using this register for example.

Not really. Typically they only have the clockdomain in common, and the
individual clocks are mostly controlled independently from each other.
For example on omap3 we have following register:
CM_FCLKEN_PER
Physical Address 0x4800 5000
BIT31:19 RESERVED Write 0s for future compatibility. Read returns 0.
BIT18 EN_UART4 UART4 functional clock control.
BIT17 EN_GPIO6 GPIO6 functional clock control.
BIT16 EN_GPIO5 GPIO5 functional clock control.
BIT15 EN_GPIO4 GPIO4 functional clock control.
BIT14 EN_GPIO3 GPIO3 functional clock control.
BIT13 EN_GPIO2 GPIO2 functional clock control.
BIT12 EN_WDT3 WDT3 functional clock control.
BIT11 EN_UART3 Type UART3 functional clock control.
BIT10 EN_GPT9 GPTIMER 9 functional clock control.
BIT9 EN_GPT8 GPTIMER 8 functional clock control.
BIT8 EN_GPT7 GPTIMER 7 functional clock control.
BIT7 EN_GPT6 GPTIMER 6 functional clock control.
BIT6 EN_GPT5 GPTIMER 5 functional clock control.
BIT5 EN_GPT4 GPTIMER 4 functional clock control.
BIT4 EN_GPT3GPTIMER 3 functional clock control.
BIT3 EN_GPT2 GPTIMER 2 functional clock control.
BIT2 EN_MCBSP4 McBSP 4 functional clock control.
BIT1 EN_MCBSP3 McBSP3 functional clock control.
BIT0 EN_MCBSP2 McBSP 2 functional clock control.
So multiple drivers will be using this register for example.

Ref and bypass clocks are used currently by all DPLLs (also the APLL) so
I guess I just enforce both to be specified.

Hmm so, should I add a stub representation for the clockdomains to the
DT then for now or how should this be handled? The stubs could then be
mapped to the actual clock domains based on their node names.

The point I was trying to get across is that this looks like a single
logical block which controls the (independent) gating of several clocks,
along the same lines as multiple swtiches bound together in a DIP
switch.
It's equally valid to view that as several clock gates which happen to
have their control bits in close proximity in the memory map, as you
suggest.

Currently it seems if the clocks share a register, they are in the same
clockdomain (I guess this is something that might also change in
future.) The input clocks can be different (some are using the same),
and the outputs are routed to different destinations on the SoC. For the
below example, GPTs can have either sys_ck or 32k_ck as parent, UARTs
are fed from 48M clock etc.

For clarity, I think it is better to have the clocks as separate nodes,
as otherwise specifying the mapping for individual clocks becomes a pain
for the layers that are going to use the clock mapping. You would end up
with obfuscated name for UART3 / GPTIMER5 for example, and this would be
rather error prone approach also if I understand your point correctly.

Ok. It's always possible to add clock-names later if a platform doesn't
wire an input. We lose the possibility of future compatibility, but
backwards compatibility is easy enough to maintain.

I unfortunately don't have a good answer here, because I'm not that
familiar with how we handle clockdomains for power management purposes.
As I understand it, each clock domain is essentially a clock gate
controlling multiple clock signals, so it's possible to describe that
with the common clock bindings, with a domain's clocks all coming from a
"domain-gate-clock" node (or something like that). That would make the
wiring of clocks to a domain explicit and in line with the rest of the
common clock bindings. But perhaps I've simplified things a bit too
far.
I'm not sure how easy it would be to use that information for power
management. I don't know what the kernel logic for clock domain power
management needs to know about consumers of the clocks and how it would
need to poke those consumers.
Cheers,
Mark.

You got it basically right, but maybe oversimplified it a bit. The
root/parent clocks can still cross clockdomain boundaries, so mapping
everything under a simple clockdomain gate would not work. Basically
each clock has a mapping on the SoC for both its parent clock signal and
the clockdomain association, kind of having two parents at the same
time. In OMAP case, most of the clockdomains support hardware autoidle
type functionality, which puts the domain to idle once all the clocks on
it are disabled.

I'm not sure that this binding should know about the clock domain at
all. Maybe the clock domain binding should list the clocks that are
within the domain?

I always thought that OMAP clock domains were poorly named. Seems to me
that they had more to do with the IP/module programming than clocks per
se. Again, I'm not sure that putting clkdm data into this binding is
correct.
Is it because you want a call to clk_enable to program the clock domain
in the .enable callback? I always thought that this was better left to a
pm_runtime_get callback...

It was more taking the reference from omap2 code. raw_readl can be used.

It was more taking the reference from omap2 code. raw_readl can be used.

Ok, I experimented with this stuff a bit to have a proper reply, and it
looks like I can get this done with a clockdomain mapping, which has its
own binding. Something like this:
clockdomains {
usbhost_clkdm: usbhost_clkdm {
compatible = "ti,clockdomain";
clocks = <&usbhost_48m_fck>, <&usbhost_ick>;
};
};
Mike, what is your approach on this? Are you okay having the
implementation for this under drivers/clk? I recall you mentioned
earlier that you don't want clockdomain stuff under drivers/clk, hence I
am asking.
Here is the initial implementation for the binding:
void __init of_omap_clockdomain_setup(struct device_node *node)
{
struct clk *clk;
struct clk_hw *clk_hw;
const char *clkdm_name = node->name;
int i;
int num_clks;
num_clks = of_count_phandle_with_args(node, "clocks",
"#clock-cells");
for (i = 0; i < num_clks; i++) {
clk = of_clk_get(node, i);
if (__clk_get_flags(clk) & CLK_IS_BASIC) {
pr_warn("%s: can't setup clkdm for basic clk %s\n",
__func__, __clk_get_name(clk));
continue;
}
clk_hw = __clk_get_hw(clk);
to_clk_hw_omap(clk_hw)->clkdm_name = clkdm_name;
omap2_init_clk_clkdm(clk_hw);
}
}
CLK_OF_DECLARE(omap_clockdomain, "ti,clockdomain",
of_omap_clockdomain_setup);

My guess is that some clocks require the clockdomain itself to be forced
on before they are enabled, some of the DPLLs do this for example. I am
just trying not to cause any regressions with this set, thus attempting
to keep most of the implementation specifics intact.

Cool, this is much closer to what I had in mind. I guess the clock
domain DT binding can be marked as "Unstable - ABI compatibility may be
broken in the future" since the binding isn't really fleshed out yet.

I do not want them to live there permanently. There has been some talk
about drivers/syscon/ or whatever for a while now, but this clkdm stuff
is also not a good candidate for that since none of the clkdm bits here
are really fleshed out with an eye towards a reusable core framework.
Maybe someday though...
I guess I could take it into drivers/clk/ti/ on a temporary basis, with
a commitment to move it out when the right driver infrastructure for
clock domains comes along.

Hi Russell,
After looking at this a bit more, it seems difficult to get rid of the
clk_get -> of_clk_get conversion, however based on this comment I am
somewhat stuck. Do you think it would be acceptable if I change the
implementation of this patch to work like this:
1) both dev_id + con_id defined:
a) search for device node named dev_id
b) check clock-names for matching con_id
c) return matching clock
Example in kernel:
clocksource-nomadik-mtu.c :
clk_get_sys("mtu0", "apb_pclk");
ste-nomadik-snt8815.dts:
mtu0: mtu@101e2000 {
/* Nomadik system timer */
compatible = "st,nomadik-mtu";
reg = <0x101e2000 0x1000>;
interrupt-parent = <&vica>;
interrupts = <4>;
clocks = <&timclk>, <&pclk>;
clock-names = "timclk", "apb_pclk";
};
2) dev_id = NULL, con_id defined (current patch implementation, most of
the OMAP clocks use this approach):
a) search for a device node named con_id
b) return corresponding clock from the node
Alternatively I must implement a regression and break some of the OMAP
drivers with this set, and also implement omap internal clk_get
functionality (basically adding a similar wrapper that I have
implemented in this patch) under mach-omap2 to get some basic OMAP infra
to work properly (namely, hwmod.) I can probably avoid part of this by
adding more beef to the *.dts files for the critical parts to get boot
working at least.

Firstly, for clk_get(), you don't need to do anything - clk_get() already
deals with DT, and if your DT is correct, it should already be returning
the appropriate clock(s).
I guess the problem here is clk_get_sys(), because that doesn't take a
struct device (and it doesn't take a struct device because it's used
from code where there is no struct device to use with it.)
If you have an OF node, what's wrong with using of_clk_get_by_name()?
If you don't have an OF node, how do you expect to find the clock in

Firstly, for clk_get(), you don't need to do anything - clk_get() already
deals with DT, and if your DT is correct, it should already be returning
the appropriate clock(s).
I guess the problem here is clk_get_sys(), because that doesn't take a
struct device (and it doesn't take a struct device because it's used
from code where there is no struct device to use with it.)
If you have an OF node, what's wrong with using of_clk_get_by_name()?
If you don't have an OF node, how do you expect to find the clock in
the device tree, remembering that clocks are specific to devices, and
the 2nd argument to clk_get()/clk_get_sys() is not a unique identifier.

Yeah, most of the OMAP clocks have been traditionally referenced in this
way, they are using clk_get_sys and with dev=NULL. conn-id is mostly unique.

In the legacy code, pretty much all the clocks are mapped through
clk_get_sys(NULL, conn), and large amount of the drivers don't even have
DT conversion in place yet. I am attempting to handle the cases where we
don't have OF nodes.... yet at least, without converting everything to
DT, and without causing regressions (also, I don't even pretend to be
capable of testing all the potential drivers for this.) Some parts of
the basic infra which are using clk_get_sys are pretty silly also, like
the ocp_if parts of the hwmod, I haven't figured out yet how to convert
that to DT.
Personally I don't mind causing a regressions here though, if I get
approval for it from Tony.

No, let's not do that. We don't want to break existing drivers.
How about initialize the platform driver clocks in the clock driver
and set up the clock alias? Then when the driver is fixed for DT,
those can be dropped one at a time.
