[PATCH v4 4/7] media: venus: hfi: Skip AON register programming for V6 1pipe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



AON register programming is used to set NOC to low
power mode during V6 power off sequence. However
AON register memory map is not applicable to 1pipe,
hence skipping AON register programming.
