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

[PATCH 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.

[PATCH 1/6] soc: amlogic: modify some power domains property

[Xianwei Zhao]

From: "xianwei.zhao" <xianwei.zhao@amlogic.com>

Some power domains for C3 can be using runtime PM,
remove ALWAYS_ON property. And add some power domains
description when ALWAYS_ON property.
