   4 Subject: [PATCH] ARM: sun7i: dt: Fixup mmc bindings
   5
   6 1) Now that we're no longer overriding the caps set by mmc_of_parse we need
   7 to set cd-inverted for our card detection to work.
   8
   9 2) Now that we no longer claim UHS modes support we will never use any DDR
  10 modes, so drive-strength 2 is enough for the mmc data pins.
