Hi Vinod,

this has been picked up by Hector and is staged in asahi-soc/dt [0].
I see you haven’t pushed yet. Would it be possible to drop the patch
on your end so we don’t end up with two commits for the same change?
(I assume that would be an issue.)

To recapitulate: There are two ADMAC binding changes to go in for 6.1,
they are both in asahi-soc/dt. I know I initially asked you to apply
this patch when the series was an RFC.

Thanks,
Martin
