It would have been useful to have provided that feedback at the time
rather than waiting until after it had been merged - it was in review
for long enough.  It would also be good to articulate the issues with
the binding rather than simply stating they exist, and to consider
adding a second binding to the existing generic card rather than adding
a totally new card.

Please also remember that all DT patches need to be reviewed by the DT
people, you've not CCed either them or the list.

These are Linux-internal concepts which shouldn't appear in a DT binding
or at the very least need definition.  One thing to consider here is
that these things are all about the internals of a SoC and you'd
therefore expect that they would be defined separately from the card so
as to avoid having to replicate information in every card using a given
