I can queue this to fbdev tree, but how do you want to handle the second
patch? I think these two patches are independent, so the second patch
could go via arm-soc tree (or whichever is the normal route for those
.dts file changes). I'd prefer that option.

If these need to go together, I need acks for the second patch.
