Cover letter [RFC 0/3] ARM: sun9i: Add PRCM clocks and reset controls support
Hi Chen-Yu,
Quoted 10 lines · Chen-Yu Tsai
This series adds basic support for the PRCM module on sun9i, which has clock and reset controls for the CPU-S or RTC block.
The series is marked RFC, because we do not have actual documentation for it. I am assuming the clock tree and register format is the same as the A31 and A23. Obviously we will need to do some testing to verify, which we would need actual peripherals to do.
I'm posting this so Maxime can test his pinctrl drivers, and then we can work out how to verify the clocks.
This looks fine overall, but I'm a bit worried that there is too much that we don't really know about in this.
Do we need it right now, or can it wait for some A80 documents to be released? Maybe we can just postpone this until we have more informations on this if it's not going to be used anytime soon anyway.
Maxime
