There are 4 clock controllers in A9 SoC:
- SCMI clock controller: these clocks are managed by the
Trusted Firmware-A(TF-A) and handled through SCMI.
- PLL clock controller.
- peripheral clock controller.
- AO clock controller.
There are reserved register regions placed between individual PLLs, so a
separate driver is implemented for each PLL, similar to T7.
Compared to previous SoCs PLLs, the A9 PLL controller introduces 4 new features:
1.PLL l_detect signal supports active-high configuration.
Previous A7 and T7 l_detect signals are active-low.
2.PLL reset signal supports active-low configuration.
Previous reset signals are active-high.
3.Support POWER_OF_TWO for the PLL pre-divider N;
the N pre-divider follows the same calculation rule as OD.
4.The PLL input path includes an inherent divide-by-2 divider.
Implement the first three features in clk-pll.c (verified on A9 and T7),
with no impact to PLL logic on existing SoCs. Add a fixed divide-by-2 to
A9 PLL driver for the fourth feature.
A9 PLL is composed as follows:
PLL
+---------------------------------+
| |
| +--+ |
in/2 >>---[ /2^N ]-->| | +-----+ |
| | |------| DCO |----->> out
| +--------->| | +--v--+ |
| | +--+ | |
| | | |
| +--[ *(M + (F/Fmax) ]<--+ |
| |
+---------------------------------+
out = in / 2 * (m + frac / frac_max) / 2^n

l_detect controls the enable/disable of the PLL lock-detect module.
For A9, the l_detect signal is active-high:
0 -> Disable lock-detect module;
1 -> Enable lock-detect module.
Here, a flag CLK_MESON_PLL_L_DETECT_ACTIVE_HIGH is added to handle cases
like A9, where the signal is active-high.

In the A9 design, the PLL reset signal is configured as active-low.
Add the flag 'CLK_MESON_PLL_RST_N' to indicate that the PLL reset signal
is active-low.

The A9 PLL pre-divider uses a division factor of 2^n to ensure a clock
duty cycle of 50% after predivision.
Add flag 'CLK_MESON_PLL_N_POWER_OF_TWO' to indicate that the PLL
pre-divider division factor is 2^n.

hifi isn't in the dt bindings. Should this be hifi0 and/or hifi1?

You can use CLK_HW_INIT_HWS() here.

I'll only flag new things that I spot here that weren't mentioned in
the other patches I reviewed in this series.

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The schema conditional block for MCLK PLLs fails to enforce the required second clock input, allowing incomplete device tree nodes to pass validation.

Does this conditional block also need to specify minItems: 2 for the clocks
and clock-names properties?
The global property definition describes the second clock as a fixed input
clock source without the (optional) designation given to the third clock.
Since the global minItems is 1, omitting a stricter minItems constraint
here causes a schema validation regression where an incomplete device tree
node specifying only a single clock for an MCLK PLL will silently pass,
even though it is missing the mandatory second input.

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [High] The `meson_clk_pll_disable` function was not updated to handle the new `CLK_MESON_PLL_RST_ACTIVE_LOW` flag, causing it to incorrectly de-assert the reset signal instead of asserting it.
- [Medium] The flag name documented in the commit message does not match the actual code implementation.

commit c5af3b10e7a77c9b06f4a72f2dacfc47fec10acf
Author: Jian Hu <jian.hu@amlogic.com>
clk: amlogic: PLL reset signal supports active-low configuration
In the A9 design, the PLL reset signal is configured as active-low.
Add the flag 'CLK_MESON_PLL_RST_N' to indicate that the PLL reset signal
is active-low.
> Add the flag 'CLK_MESON_PLL_RST_N' to indicate that the PLL reset signal

This isn't a bug, but the commit message says 'CLK_MESON_PLL_RST_N' while
the code defines CLK_MESON_PLL_RST_ACTIVE_LOW. Could the commit message
be updated to match the code?

Since active-low PLLs use 0 to assert the reset here, does
meson_clk_pll_disable() also need to be updated to respect the
CLK_MESON_PLL_RST_ACTIVE_LOW flag?
Currently it unconditionally writes 1 to assert reset:
drivers/clk/meson/clk-pll.c:meson_clk_pll_disable() {
...
/* Put the pll is in reset */
if (MESON_PARM_APPLICABLE(&pll->rst))
meson_parm_write(clk->map, &pll->rst, 1);
...
}
If this is an active-low PLL, wouldn't writing 1 de-assert the reset when
the clock is disabled, potentially causing hardware state inconsistencies?

Should linux/module.h be included in this file since it uses several
module-specific macros?
Relying on implicit inclusion via other headers like linux/platform_device.h
can sometimes lead to build failures on different architectures or in future
kernel versions if header dependencies change.

^^^^
Since channels 5 and 6 are unconnected, should this macro use a value table
similar to a9_usb_250m_parents_val_table?
Passing NULL might cause the framework to write the unconnected index 5 for
the fdiv2p5 clock, potentially silencing the clock output instead of
selecting index 7.

^^
Could this cause a register bit overlap?
The divider is configured to be 12 bits wide starting at bit 0, which means
it occupies bits 0 through 11. However, the clock gate is also defined at
bit 11 in the same register.
Writing to the divider might inadvertently toggle the clock gate, and
toggling the gate could corrupt the most significant bit of the divider.

^^^^^^^^^^^^^^^^^^^^^^^
Is this the intended parent selector?
This references a9_hdmitx_pixel_sel instead of a9_hdmitx1_pixel_sel. This
hierarchy mismatch might cause parent and rate adjustments for hdmitx1_pixel
to mutate the wrong clock selector, leaving its own hardware unconfigured.

Thank you for your contribution! Sashiko AI review found 3 potential issue(s) to consider:
- [High] The clock gate for `ao_pwm_b` incorrectly writes to the `AO_PWM_CLK_A_CTRL` register instead of `AO_PWM_CLK_B_CTRL`.

clk: amlogic: Add A9 AO clock controller driver
This commit introduces the Always-on clock controller driver for the Amlogic
A9 SoC family. It adds the clock definitions and registers the platform
driver for the A9 AO clocks.

This isn't a bug, but should <linux/module.h> be explicitly included here?
The driver uses MODULE_DESCRIPTION, MODULE_AUTHOR, MODULE_LICENSE,
MODULE_IMPORT_NS, and MODULE_DEVICE_TABLE macros, which rely on this header.
[ ... ]
> +static A9_AO_PCLK(i2c3, 0, 0);
This isn't a bug, but should this be named i3c instead of i2c3?
This is later mapped to the CLKID_AO_SYS_I3C enum, so the dt-bindings and
the hardware clock name appear to be mismatched.

Could the gate for ao_pwm_b be incorrectly writing to AO_PWM_CLK_A_CTRL
instead of AO_PWM_CLK_B_CTRL?
If so, toggling the ao_pwm_b clock will modify the gate bit for ao_pwm_a,
which could cause uncoordinated toggling of the ao_pwm_a hardware state
and fail to actually control the ao_pwm_b clock.

This isn't a bug, but is there a typo in the clock name "ao_rtc_duandiv_in"?
It looks like it should be "ao_rtc_dualdiv_in".

Yes, You are right, the flag should indeed be CLK_MESON_PLL_RST_ACTIVE_LOW.
I will fix the description in the next version.
Thank you for pointing it out.

Ok, I will use CLK_HW_INIT_HW instead for single parent case.

Ok, I will place them in order.
After updated:

#include <linux/clk-provider.h>
#include <linux/platform_device.h>
#include "clk-regmap.h"

It should be hifi0，I will fix it in the next version.
Thank you for pointing it out.

Got you, I will sort the header, also use
CLK_HW_INIT_FW_NAME/CLK_HW_INIT_HWS for this driver.

Yes, it should be AO_PWM_CLK_B_CTRL.
