- if (status_change_8to11 & AMD_SDW_WAKE_STAT_MASK)
return amd_sdw_process_wake_event(amd_manager);it's not clear what 8to11 might have to do with the wake enable?
Can't you have a wake for devices 1..7?
It can wake any device from 1..11 . SoundWire Wake interrupt status bit is part of 8to11 register.
You probably want to explain what status_change_0to7 and status_change_8to11 actually control, it's not very intuitive for me to see device 1 interrupt being handled in status_change_8to11?
