Subject: [PATCH] ARM: sun5i: 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.
|
||
|
|
|
||
|
|
3) mmc1 on the A13 is not routed to any pins, and thus unusable, remove it
|
||
|
|
from the dtsi
|
||
|
|
|
||
