As far as I know, tested-on is not documented anywhere (and isn't
really used either). I've removed it and applied, thanks!

I normally add it as a comment following the Tested-by. Makes it
easier to track who tested what when patches touch multiple
boards.

I think this patch should go through my tree as it refers to a commit in
my branch.

I'm not quite sure to get why. Even though that patch depends on the
one affecting the driver to be functional, it doesn't break anything
when merged through arm-soc, and similarly yours doesn't affect any
other tree if it's merged through your tree, so there's no dependency?

Sorry, I puzzled myself, I thought you meant you applied patch 1/2

HI Chen-Yu and Maxime,

Can you pick this up again?

Sorry, I'm not quite sure what happened to this patch... I've picked
it up for 5.7 (for real this time, hopefully).
