soc: apple: apple-pmgr-pwrstate: Do not build as a module

2021-12-15T11:36:05Z

This doesn't make any sense as a module since it is a critical device, and it turns out of_phandle_iterator_args was not exported so the module version doesn't build anyway.

soc: apple: apple-pmgr-pwrstate: Add auto-PM min level support

This is seemingly required for DCP/DCPEXT, without which they refuse to boot properly. They need to be set to minimum state 4 (clock gated). Reviewed-by: Sven Peter Signed-off-by: Hector Martin

soc: apple: Add driver for Apple PMGR power state controls

2021-12-07T04:13:13Z

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 (clockgate-only state, misc flags), 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. Acked-by: Linus Walleij Signed-off-by: Hector Martin
