The patch seems fine to me, but you should address it at the 
TI K3 maintainers, so they know they should apply it and forward
it to the SoC tree. You have Nishanth and Vignesh in Cc already,
so I assume they will pick it up from here, just put them in
'To' instead next time and move Catalin and Will to 'Cc' or
leave them off entirely.
