Then how do we deal with boards which use a different gpio for card-detect ? In that case we don't want to change the mux setting of the reference design cd pin. IOW I believe that having 2 separate pinctrl settings for this is the rigt thing todo. I would prefer using just mmc0_cd_pin_a instead of _reference_design though.

There's already a documented default that is 1. Plus, I still believe in a strict separation between what's in the SoC being in the DTSI and what's in the board being in the DTS. Apart from being more rigorous, it also has the advantage of being *much* clearer whenever your read a board DTS, since you don't have to actually open several DTS(I) to get what's going on.
