Many SoCs allow power to be applied to or removed from portions of the SoC (power domains). This may be used to save power. This API provides the means to control such power management hardware.

I'll soon(?) send a Tegra186 power domain driver that implements this new subsystem. I'm waiting for all the relevant DT bindings to be reviewed as kernel patches first though.

Could you add a command (with list/on/off subcommands) to control this also?
Any thoughts on this?
Applied to u-boot-dm, thanks!
