[PATCH v4 0/3] pwm: meson: add pwm support for A1

[PATCH v4 0/3] pwm: meson: add pwm support for A1

[George Stark]

Add support for Amlogic meson A1 SoC family PWM

Changes in v2:
  add patch with optional power-domains to pwm bindings;
  fix syntax in a1 bindigns patch:
  - use enum over const for amlogic,meson-a1-pwm beacuse adding more devices here
    are expected
  - leave only base compatible amlogic,meson-s4-pwm in check section
  dt_binding_check and dtbs_check run ok now;
  previous version: [1]

Changes in v3:
  squash power-domains patch into main bindigns patch
  add conditional to bindings that power-domains property is required only for a1
  previous version: [2]

Changes in v4:
  split bindings patch into power-domains patch and new compatible patch
  previous version: [3]

[PATCH v4 1/3] dt-bindings: pwm: amlogic: Add optional power-domains

[George Stark]

On newer SoCs, the PWM hardware can require a power domain to operate
so add corresponding optional property.

[PATCH v4 3/3] arm64: dts: meson: a1: add definitions for meson PWM

[George Stark]

The chip has 3 dual-channel PWM modules PWM_AB, PWM_CD, PWM_EF those
can be connected to various digital I/O pins.

Each of 6 PWM is driven by individually selected clock parent and
8-bit divider. The PWM signal is generated using two 16-bit counters.

Missing ack from Conor. When you submit new versions, it is your

I had Conor's ack in my mind but his response was related to the
squashed patch (a1 compatible + power domains) and the current patch was
a bit different that's why I didn't dare to add the ack.

Conor, do you mind if I resend this patch (and may be [PATCH v4 1/3])
with your ack?

The known issue with this series is just that it's one of several patch
series that I didn't come around to review yet. I tackle them one at a
time, usually in a FIFO order as listed on
https://patchwork.ozlabs.org/project/linux-pwm/list/ .

I interpreted that as an ack for patches 1 and 2 and applied these to
https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux.git pwm/for-next
. I guess that interpretation is fine, please tell me if not.

Yah, I was okaying my ack being added to both patches in a resend.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.13/arm64-dt)

[3/3] arm64: dts: meson: a1: add definitions for meson PWM
      https://git.kernel.org/amlogic/c/b7e5f4bb555ba1d4fdad6f94eb6ab9f8d9c63597

These changes has been applied on the intermediate git tree [1].

The v6.13/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
