Can you please take a look into this series? I'd like them to be added
in the next merge window and if something needs to be changed I'd like
to have a bit of time to do it :)).

Regarding how to merge this I guess all of the patches should apply
cleanly in any tree but since there are already changes in mt7621-dts
maybe patches 1 and 4 which are related can go through the staging
tree (if Greg is ok with this) and the bindings doc change and driver
changes (patches 2 and 3) can go through your tree.

Thanks in advance for your time.

Best regards,
    Sergio Paracuellos
