BTW, [1] your patches 7/8 and 8/8 never hit the mailing list, So, I am
commenting on the defconfig patches without actually seeing the patches,
and solely based on $subject in the cover letter.

The reason for my comment was that I think defconfig series could go
independent of the remaining series into 5.10, since they are not
related specifically to this series, they are probably needed even for
am654 and j721e nodes that already exist and was a miss that we didn't
enable. Tying that to this specific series didn't make sense to me.

But either way, we are way past rc7. I don't have enough time for
these patches to bake in -next to make it to 5.10 window. So, lets try
reposting this after rc1 tag is done so that I can send the defconfig
(separately for 5.10 window) and the dts staged towards 5.11 (and no,
I don't consider the dts patches as fixes - they are enabling the next
level of functionality).
