[PATCH v2 0/3] amlogic SoC's power-domains fixes

[George Stark]

Here's some fixes to the bindings and device tree related to Amlogic A1 SoC.
The SoC provides dedicated power domain for for almost all periphery.

Changes in v2:
  dt-bindings: spi: amlogic,a1-spifc: make power-domains required
    - drop the patch
  dt-bindings: thermal: amlogic,thermal: add optional power-domains
    - drop required conditional
    - rewrite commit message
  dt-bindings: i2c: amlogic,meson6-i2c: add optional power-domains
    - add RvB: Neil Armstrong <neil.armstrong@linaro.org>

[PATCH v2 1/3] dt-bindings: i2c: amlogic,meson6-i2c: add optional power-domains

[George Stark]

On newer SoCs, the I2C hardware can require a power domain to operate.
Since the same compatible is used for older and newer SoCs make
power-domains property optional.

[George Stark]

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

Re: [PATCH v2 0/3] amlogic SoC's power-domains fixes

[George Stark]

Hello

 From this series i2c patch was applied.
Are the thermal sensor's dts and bindings patches ok? Should I do 
anything on it?

I'll take patch 3 after patch 2 is applied on thermal tree.

Daniel could you take patch 2 ?

Thanks,
Neil

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: bind power domain to temperature sensor
      https://git.kernel.org/amlogic/c/7e3b4f56a76b233a70db09ddaa5e822f7cddf371

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.
