In general I think this makes sense, but we need to make sure that
patch3 is merged before we drop the mshc alias support in the dw_mmc
driver, so please re-order the patches in the series to make this
clear.

If we agree that the $subjeect series makes sense, I could potentially
help by taking the DTS patch too via my mmc tree.

Kind regards
