Hector Martin	cc1fe1e54b	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 <sven@svenpeter.dev> Signed-off-by: Hector Martin <marcan@marcan.st>	2021-12-12 10:32:10 +09:00
Hector Martin	6df9d38f91	soc: apple: Add driver for Apple PMGR power state controls ... 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.
