Signed-off-by: Enric Balletbo i Serra Reviewed-by: Chanwoo Choi Acked-by: Rob Herring Signed-off-by: Gaël PORTAY Acked-by: MyungJoo Ham --- Following the discussion in [1] and after having [2] accepted, this patch is a RESEND of a patch [3] that has already all the acks but for some reason and my bad, I lost the tracking, didn't land. The patch adds documentation for an already property implemented in the driver, so resend the patch again. There is a slighty modification, the rockchip,pmu property has been moved to be optional as is not really required.
