A1 SoC has four clock controllers on the board: PLL, Peripherals, CPU,
and Audio. The audio clock controller is different from others, but the
rest are very similar from a functional and regmap point of view.
This patch series add support for Amlogic A1 PLL and Peripherals clock
drivers.
It blocks all A1 peripherals mainline support and a couple of patch series,
which were already reviewed and acked, but weren't merged due to pending
clock controller drivers series, e.g.
https://lore.kernel.org/linux-amlogic/7hd09cw9oh.fsf@baylibre.com/
TODO: CPU and Audio clock controllers are not included in this patch
series, it will be sent later. The following clks from these controllers
are not supported for now:
* Audio clks - vad, mclk_vad, mclk_d, resample_a, locker_in, mclk_b,
pdmdclk, pdmsysclk, eqdrc, spdifin, mclk_a, audio2_toaudiotop,
audio2_tovad, audio2_toddr_vad, audio2_tdmin_vad, audio2_pdm,
audio2_ddr_arb, audio_audiolocker, audio_eqdrc, audio_resamplea,
audio_spdifin, audio_toddrb, audio_toddra, audio_frddrb, audio_frddra,
audio_tdmoutb, audio_tdmouta, audio_loopbacka, audio_tdminlb,
audio_tdminb, audio_tdmina, audio_ddr_arb, mclk_c
* CPU clks: cpu_fixed_source_sel0, cpu_fixed_source_div0,
cpu_fixed_source_sel1, cpu_fixed_source_div1, cpu_clk
Validation:
* to double check all clk flags run below helper script:
pushd /sys/kernel/debug/clk
for f in *; do
if [[ -f "$f/clk_flags" ]]; then
flags="$(cat $f/clk_flags | awk '{$1=$1};1' | sed ':a;N;$!ba;s/\n/ | /g')"
echo -e "$f: $flags"
fi
done
popd
* to trace current clks state use '/sys/kernel/debug/clk/clk_dump' node
with jq post-processing:
$ cat /sys/kernel/debug/clk/clk_dump | jq '.' > clk_dump.json
* to debug clk rate propagation, compile kernel with the following
definition:
$ sed -i "s/undef CLOCK_ALLOW_WRITE_DEBUGFS/define CLOCK_ALLOW_WRITE_DEBUGFS/g" drivers/clk/clk.c
after that, clk_rate debug node for each clock will be available for
write operation
Changes v12 since v11 at [12]:
- split the DT bindings patchset into two patches: one for the PLL clock
controller driver, and one for the peripherals clock controller driver
- to satisfy the DT binding checker, use fake references to the
peripherals clock controller in the PLL DT bindings schema, and then
replace them with real references when the peripherals bindings
become available.
- remove the public/private clocks concept from both controllers,
and instead use a linear clkid list with both exposed and internal
objects, all of which are registered in the clock provider
- combine all comments about RTC children with the flag
'CLK_SET_RATE_NO_REPARENT' into a single item with multiple
references to it
Changes v11 since v10 at [11]:
- change include/dt-bindings license to proper value required for
bindings files: 'GPL-2.0-only OR BSD-2-Clause'
- pll and peripherals clocks are split into public and private parts;
public clocks are available for external consumers through the DT layer,
private clocks include internal muxes and dividers of composite clocks,
they are placed inside clock controller driver without external access
- make public clks CLKID bindings continuous
- mark the following clock muxes as NO_REPARENT and add them to
public clocks list: GEN_SEL, DSPA_A_SEL, DSPA_B_SEL, DSPB_A_SEL,
DSP_B_B_SEL, PWM_A_SEL, PWM_B_SEL, PWM_C_SEL, PWM_D_SEL,
PWM_E_SEL, PWM_F_SEL, CECA_32K_SEL, CECB_32K_SEL; each of them can
be inherited from more accurate RTC clock and sometimes it's
required to forbid reparenting in such situation; also GEN_SEL can
be connected to external PAD and should not change parent
automatically due to rate propagation. For such clocks user must
setup parents on the DT side
Changes v10 since v9 at [10]:
- split general clk-pll changes into two different patchsets:
optional rst usage and new power sequence
- squash dt bindings patchsets to avoid chicken-or-the-egg problem
during run dt binding check routines
- add vendor prefix to PLL and Peripherals clkcs bindings filenames
- clear managed hifi_pll fields from initial poke table
- move DSPA_SEL, DSPB_SEL and SARADC_SEL to private clkid table,
because it should not be opened for direct usage
- pwm_a clk used for voltage regulation is not critical anymore, it
must be included to the proper cpu voltage regulation setup (will
be available in the next patch series)
- as discussed with Jerome, dspX clks are simple clocks and it
should be enabled/disabled/ignored/anything else from appropriate
DSP driver, so remove CLK_IGNORE_UNUSED tags
- provide more understandable comments and remove irrelevant (I hope so)
- remove CONFIG_OF usage, because it's redundant
- fix license issue, it's GPL-2.0+ only in the current version
- some commit msgs rewording
Changes v9 since v8 at [9]:
- remove common a1-clkc driver for the first version of a1 clock
controllers as Jerome suggested (it will be discussed after s4 and
a1 clks landed, hope so)
- replace inherited a1-pll clk_pll_ops with common ops and
introduce custom A1 PLL logic under MESON_PARM_APPLICABLE()
conditions
- rename xtal depended clocks in PLL and Peripherals domains
- remove 'a1_' prefix for all clocks, because they are already
inside A1 driver, it's redundant
- change udelay() to usleep_range() as preferred for small msec
amount
- purge all double quotes from the yaml schemas
- use proper dt node names following kernel guidelines
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation
- use devm_platform_ioremap_resource() instead of simple
devm_ioremap_resource()
- mark all dspX clocks as CLK_IGNORE_UNUSED, because we do not want
to touch these clocks during CCF initialization due to possible
workload execution on it started from bootloader; in this case
bootloader already made all initialization stuff for dspX
- also mark all dspX with NO_REPARENT tag, because from dspX clocks
we want to select proper clk source from device tree
Changes v8 since v7 at [8]:
- introduced a1-clkc common driver for all A1 clock controllers
- exported meson_clk_pll_wait_lock symbol
- supported meson-a1-clkc common driver in the a1-pll and a1 clkc
- inherited a1-pll from the base clk-pll driver, implemented own
version of init/enable/disable/enabled routines; rate calculating
logic is fully the same
- aligned CLKID-related definitions with CLKID list from order
perspective to remove holes and permutations
- corrected Kconfig dependencies and types
- provided correct MODULE_AUTHORs()
- optimized and fixed up some clock relationships
- removed unused register offset definitions
- fixed up A1 PLL and Peripherals clkc dtb_check errors
- fixed clk_summary kernel panic due to missing a1_pad_ctrl
clk_regmap definition
- included PLL and Peripherals clk controllers to the base a1 dts
- The previous v7 version [8] had several logic and style problems,
all of them are resolved in this version. Original Jian Hu v7 patches
are not touched, and all additional fixes are implemented in separate
patches. Patch "clk: meson: add support for A1 PLL clock ops" is
removed, because a1-pll clk driver inherits all stuff from clk-pll
base driver, just implements custom init/enable/disable/is_enabled
callbacks.
Changes v7 since v6 at [7]:
- fix 'dt_binding_check' compiling error
- add acked-by
Changes v6 since v5 at [6]:
- fix yaml file
- add rst/current_en/l_detect parm detection
- remove 'meson_eeclkc_data' in a1.c and a1-pll.c
Changes v5 since v4 at [5]:
- change yaml GPL
- drop meson-eeclk.c patch, add probe function in each driver
- add CLK_IS_CRITICAL for sys_clk clock, drop the flag for sys_a
and sys_b
- add new parm for pll, add protection for rst parm
- drop flag for a1_fixed_pll
- remove the same comment for fclk_div, add "refer to"
- add critical flag for a1_sys_clk
- remove rtc table
- rename a1_dspa_en_dspa and a1_dspb_en_dspb
- remove useless comment
Changes v4 since v3 at [3]:
- fix reparenting orphan failed, it depends on jerome's patch [4]
- fix changelist in v3 about reparenting orphan
- remove the dts patch
Changes v3 since v2 at [2]:
- add probe function for A1
- separate the clock driver into two patch
- change some clock flags and ops
- add support for a1 PLL ops
- add A1 clock node
- fix reparenting orphan clock failed, registering xtal_fixpll
and xtal_hifipll after the provider registration, it is not
a best way.
Changes v2 since v1 at [1]:
- place A1 config alphabetically
- add actual reason for RO ops, CLK_IS_CRITICAL, CLK_IGNORE_UNUSED
- separate the driver into two driver: peripheral and pll driver
- delete CLK_IGNORE_UNUSED flag for pwm b/c/d/e/f clock, dsp clock
- delete the change in Kconfig.platforms, address to Kevin alone
- remove the useless comments
- modify the meson pll driver to support A1 PLLs

A1 SoC has four clock controllers on the board: PLL, Peripherals, CPU,
and Audio. The audio clock controller is different from others, but the
rest are very similar from a functional and regmap point of view.
This patch series add support for Amlogic A1 PLL and Peripherals clock
drivers.
It blocks all A1 peripherals mainline support and a couple of patch series,
which were already reviewed and acked, but weren't merged due to pending
clock controller drivers series, e.g.
https://lore.kernel.org/linux-amlogic/7hd09cw9oh.fsf@baylibre.com/
TODO: CPU and Audio clock controllers are not included in this patch
series, it will be sent later. The following clks from these controllers
are not supported for now:
* Audio clks - vad, mclk_vad, mclk_d, resample_a, locker_in, mclk_b,
pdmdclk, pdmsysclk, eqdrc, spdifin, mclk_a, audio2_toaudiotop,
audio2_tovad, audio2_toddr_vad, audio2_tdmin_vad, audio2_pdm,
audio2_ddr_arb, audio_audiolocker, audio_eqdrc, audio_resamplea,
audio_spdifin, audio_toddrb, audio_toddra, audio_frddrb, audio_frddra,
audio_tdmoutb, audio_tdmouta, audio_loopbacka, audio_tdminlb,
audio_tdminb, audio_tdmina, audio_ddr_arb, mclk_c
* CPU clks: cpu_fixed_source_sel0, cpu_fixed_source_div0,
cpu_fixed_source_sel1, cpu_fixed_source_div1, cpu_clk
Validation:
* to double check all clk flags run below helper script:
pushd /sys/kernel/debug/clk
for f in *; do
if [[ -f "$f/clk_flags" ]]; then
flags="$(cat $f/clk_flags | awk '{$1=$1};1' | sed ':a;N;$!ba;s/\n/ | /g')"
echo -e "$f: $flags"
fi
done
popd
* to trace current clks state use '/sys/kernel/debug/clk/clk_dump' node
with jq post-processing:
$ cat /sys/kernel/debug/clk/clk_dump | jq '.' > clk_dump.json
* to debug clk rate propagation, compile kernel with the following
definition:
$ sed -i "s/undef CLOCK_ALLOW_WRITE_DEBUGFS/define CLOCK_ALLOW_WRITE_DEBUGFS/g" drivers/clk/clk.c
after that, clk_rate debug node for each clock will be available for
write operation
Changes v12 since v11 at [12]:
- split the DT bindings patchset into two patches: one for the PLL clock
controller driver, and one for the peripherals clock controller driver
- to satisfy the DT binding checker, use fake references to the
peripherals clock controller in the PLL DT bindings schema, and then
replace them with real references when the peripherals bindings
become available.
- remove the public/private clocks concept from both controllers,
and instead use a linear clkid list with both exposed and internal
objects, all of which are registered in the clock provider
- combine all comments about RTC children with the flag
'CLK_SET_RATE_NO_REPARENT' into a single item with multiple
references to it
Changes v11 since v10 at [11]:
- change include/dt-bindings license to proper value required for
bindings files: 'GPL-2.0-only OR BSD-2-Clause'
- pll and peripherals clocks are split into public and private parts;
public clocks are available for external consumers through the DT layer,
private clocks include internal muxes and dividers of composite clocks,
they are placed inside clock controller driver without external access
- make public clks CLKID bindings continuous
- mark the following clock muxes as NO_REPARENT and add them to
public clocks list: GEN_SEL, DSPA_A_SEL, DSPA_B_SEL, DSPB_A_SEL,
DSP_B_B_SEL, PWM_A_SEL, PWM_B_SEL, PWM_C_SEL, PWM_D_SEL,
PWM_E_SEL, PWM_F_SEL, CECA_32K_SEL, CECB_32K_SEL; each of them can
be inherited from more accurate RTC clock and sometimes it's
required to forbid reparenting in such situation; also GEN_SEL can
be connected to external PAD and should not change parent
automatically due to rate propagation. For such clocks user must
setup parents on the DT side
Changes v10 since v9 at [10]:
- split general clk-pll changes into two different patchsets:
optional rst usage and new power sequence
- squash dt bindings patchsets to avoid chicken-or-the-egg problem
during run dt binding check routines
- add vendor prefix to PLL and Peripherals clkcs bindings filenames
- clear managed hifi_pll fields from initial poke table
- move DSPA_SEL, DSPB_SEL and SARADC_SEL to private clkid table,
because it should not be opened for direct usage
- pwm_a clk used for voltage regulation is not critical anymore, it
must be included to the proper cpu voltage regulation setup (will
be available in the next patch series)
- as discussed with Jerome, dspX clks are simple clocks and it
should be enabled/disabled/ignored/anything else from appropriate
DSP driver, so remove CLK_IGNORE_UNUSED tags
- provide more understandable comments and remove irrelevant (I hope so)
- remove CONFIG_OF usage, because it's redundant
- fix license issue, it's GPL-2.0+ only in the current version
- some commit msgs rewording
Changes v9 since v8 at [9]:
- remove common a1-clkc driver for the first version of a1 clock
controllers as Jerome suggested (it will be discussed after s4 and
a1 clks landed, hope so)
- replace inherited a1-pll clk_pll_ops with common ops and
introduce custom A1 PLL logic under MESON_PARM_APPLICABLE()
conditions
- rename xtal depended clocks in PLL and Peripherals domains
- remove 'a1_' prefix for all clocks, because they are already
inside A1 driver, it's redundant
- change udelay() to usleep_range() as preferred for small msec
amount
- purge all double quotes from the yaml schemas
- use proper dt node names following kernel guidelines
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation
- use devm_platform_ioremap_resource() instead of simple
devm_ioremap_resource()
- mark all dspX clocks as CLK_IGNORE_UNUSED, because we do not want
to touch these clocks during CCF initialization due to possible
workload execution on it started from bootloader; in this case
bootloader already made all initialization stuff for dspX
- also mark all dspX with NO_REPARENT tag, because from dspX clocks
we want to select proper clk source from device tree
Changes v8 since v7 at [8]:
- introduced a1-clkc common driver for all A1 clock controllers
- exported meson_clk_pll_wait_lock symbol
- supported meson-a1-clkc common driver in the a1-pll and a1 clkc
- inherited a1-pll from the base clk-pll driver, implemented own
version of init/enable/disable/enabled routines; rate calculating
logic is fully the same
- aligned CLKID-related definitions with CLKID list from order
perspective to remove holes and permutations
- corrected Kconfig dependencies and types
- provided correct MODULE_AUTHORs()
- optimized and fixed up some clock relationships
- removed unused register offset definitions
- fixed up A1 PLL and Peripherals clkc dtb_check errors
- fixed clk_summary kernel panic due to missing a1_pad_ctrl
clk_regmap definition
- included PLL and Peripherals clk controllers to the base a1 dts
- The previous v7 version [8] had several logic and style problems,
all of them are resolved in this version. Original Jian Hu v7 patches
are not touched, and all additional fixes are implemented in separate
patches. Patch "clk: meson: add support for A1 PLL clock ops" is
removed, because a1-pll clk driver inherits all stuff from clk-pll
base driver, just implements custom init/enable/disable/is_enabled
callbacks.
Changes v7 since v6 at [7]:
- fix 'dt_binding_check' compiling error
- add acked-by
Changes v6 since v5 at [6]:
- fix yaml file
- add rst/current_en/l_detect parm detection
- remove 'meson_eeclkc_data' in a1.c and a1-pll.c
Changes v5 since v4 at [5]:
- change yaml GPL
- drop meson-eeclk.c patch, add probe function in each driver
- add CLK_IS_CRITICAL for sys_clk clock, drop the flag for sys_a
and sys_b
- add new parm for pll, add protection for rst parm
- drop flag for a1_fixed_pll
- remove the same comment for fclk_div, add "refer to"
- add critical flag for a1_sys_clk
- remove rtc table
- rename a1_dspa_en_dspa and a1_dspb_en_dspb
- remove useless comment
Changes v4 since v3 at [3]:
- fix reparenting orphan failed, it depends on jerome's patch [4]
- fix changelist in v3 about reparenting orphan
- remove the dts patch
Changes v3 since v2 at [2]:
- add probe function for A1
- separate the clock driver into two patch
- change some clock flags and ops
- add support for a1 PLL ops
- add A1 clock node
- fix reparenting orphan clock failed, registering xtal_fixpll
and xtal_hifipll after the provider registration, it is not
a best way.
Changes v2 since v1 at [1]:
- place A1 config alphabetically
- add actual reason for RO ops, CLK_IS_CRITICAL, CLK_IGNORE_UNUSED
- separate the driver into two driver: peripheral and pll driver
- delete CLK_IGNORE_UNUSED flag for pwm b/c/d/e/f clock, dsp clock
- delete the change in Kconfig.platforms, address to Kevin alone
- remove the useless comments
- modify the meson pll driver to support A1 PLLs

Compared with the previous SoCs, self-adaption current module
is newly added for A1, and there is no reset parameter except the
fixed pll. Since we use clk-pll generic driver for A1 pll
implementation, rst bit should be optional to support new behavior.

Modern meson PLL IPs are a little bit different from early known PLLs.
The main difference is located in the init/enable/disable sequences; the
rate logic is the same.
In A1 PLL, the PLL enable sequence is different, so add new optional pll
reg bits and use the new power-on sequence to enable the PLL:
1. enable the pll, delay for 10us
2. enable the pll self-adaption current module, delay for 40us
3. enable the lock detect module

Introduce PLL clock controller for Amlogic A1 SoC family.
The clock unit is an APB slave module that is designed for generating all
of the internal and system clocks.
The SoC uses an external 24MHz crystal; there are 4 internal PLLs:
SYS_PLL/HIFI_PLL/USB_PLL/(FIXPLL), these PLLs generate 27 clock sources.

Introduce Peripherals clock controller for Amlogic A1 SoC family.
A1 SoC has four clock controllers on the board: PLL, Peripherals, CPU,
and Audio.
This patchset adds support for Amlogic A1 Peripherals clock driver and
allows to generate clocks for all A1 SoC peripheral IPs.

Introduce Peripherals clock controller for Amlogic A1 SoC family.
A1 SoC has four clock controllers on the board: PLL, Peripherals, CPU,
and Audio.
This patchset adds support for Amlogic A1 Peripherals clock driver and
allows to generate clocks for all A1 SoC peripheral IPs.

Introduce Peripherals clock controller for Amlogic A1 SoC family.
A1 SoC has four clock controllers on the board: PLL, Peripherals, CPU,
and Audio.
This patchset adds support for Amlogic A1 Peripherals clock driver and
allows to generate clocks for all A1 SoC peripheral IPs.

There is no need to make such groups within the table.
I don't think such change was requested in the previous reviews.
Also grouping the IDs the way you did is a bad idea.
1) Since the clocks are registered in the order of the table, this will
make a lot of orphans during the registration of the controller. It does
work but it is not ideal performance wise. Whenever possible, it is
better to register the clocks from the roots to the leafs.
2) These 2 nice groups are going away the minute you add another clock which
was not part of the original submission. This is why IDs have no meaning,
no even groups.

There is no need to make such groups within the table.
I don't think such change was requested in the previous reviews.
Also grouping the IDs the way you did is a bad idea.
1) Since the clocks are registered in the order of the table, this will
make a lot of orphans during the registration of the controller. It does
work but it is not ideal performance wise. Whenever possible, it is
better to register the clocks from the roots to the leafs.
2) These 2 nice groups are going away the minute you add another clock which
was not part of the original submission. This is why IDs have no meaning,
no even groups.

In my opinion, it would be clearer to have two separate lists for 'exposed'
and 'internal' clocks. Krzysztof has previously mentioned that non-linear
IDs in the bindings are not a good solution, but I understand the argument
for improved performance. Therefore, I will change the ID order from root to
leaf nodes.

In my opinion, it would be clearer to have two separate lists for 'exposed'

IDs in the bindings are not a good solution, but I understand the argument
for improved performance. Therefore, I will change the ID order from root to
leaf nodes.
