Subject: [PATCH] ARM: sun7i: 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.
|
|
