Hi,
xilinx is using this interface for very long time and we can't merge our
driver changes to Linux because of missing communication layer with
firmware. This interface was developed before scpi and scmi was
available. In connection to power management scpi and scmi are missing
pieces which we already use. There is a separate discussion how to
extend scmi to support all our use cases.
This simply patch is not adding any power management features but only
adding minimum functionality which are needed for drivers.
Thanks,
Michal
