Bjorn pointed this series at me today and I verified that it works and works well on sm8250. I agree with the cleanups suggested but otherwise a very enthusiastic: Tested-by: Jordan Crouse <jorcrous@amazon.com> One nitpick possibly for the documentation somewhere. When I tried this on my own I was using the reg base from the downstream kernel which is obviously wrong. Perhaps a line somewhere in the bindings about how you calculate the base address may help future porting efforts. Jordan
