+Subject: [PATCH] ARM: sun4i: dt: Fixup mmc bindings
+
+1) Now that we're no longer overriding the caps set by mmc_of_parse we need
+to set cd-inverted for our card detection to work.
+
+2) Now that we no longer claim UHS modes support we will never use any DDR
+modes, so drive-strength 2 is enough for the mmc data pins.
