Re: [PATCH 3/7] soc: apple: Add driver for Apple PMGR power state controls

From: Hector Martin <redacted>
Date: Wed,  6 Oct 2021 00:59:19 +0900

Implements genpd and reset providers for downstream devices. Each
instance of the driver binds to a single register and represents a
single SoC power domain.

The driver does not currently implement all features (auto-pm,
clockgate-only state), but we declare the respective registers for
documentation purposes. These features will be added as they become
useful for downstream devices.

This also creates the apple/soc tree and Kconfig submenu.
