This looks good to me! I am not sure which tree you want this to be
picked up through, but unless no other volunteers I can take it
through my mmc tree.

Although, before considering to apply, I need an ack from Scott/Arnd
for the guts driver in patch 5/8 and I need an ack from Greg for patch
7/8, where the soc_device_match() interface is added (seems like you
didn't add him on cc/to).

Kind regards
Uffe
