[PATCH V3 0/6] Power: T7: add power domain driver

[Xianwei Zhao]

First patch is that remove C3 some power domain ALWAYS_ON property.
Second patch is that add driver to support power parent node. 
Third patch is that turn on power if initial power domain with
"AWAY_ON" property state is off.

Other patchs adds power controller driver support for Amlogic T7 SoC.

Changes Since v2:
 -Modify subject.
 -Define PWRC_NO_PARENT UINT_MAX
 -Remove modification that transform is_off into 1 or 0 using !!

Changes Since v1:
 -Fix license from "GPL-2.0-only OR .*" to "GPL-2.0-only OR MIT".
 -Modify T7_NIC flag  "ALWAYS_ON"

Please re-send to Ulf Hansson <ulf.hansson@linaro.org> and
linux-pm@vger.kernel.org since this driver has moved to the
GENERIC PM DOMAIN PROVIDERS subsystem.

I'll take the DT patch since bindings patch was reviewed.

Thanks,
Neil

In fact I'll need Ulf to provide me an immutable branch or tag with
the bindings in order for me to apply the DT patch.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.7/arm64-dt)

[6/6] arm64: dts: amlogic: t7: add power domain controller node
      https://git.kernel.org/amlogic/c/5355699dabac3c97492a30e6e01820fcaae11218

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

The v6.7/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.
