Subject: arm64: allwinner: pine64: add MMC support
|
||
|
|
|
||
|
|
All Pine64 boards connect an micro-SD card slot to the first MMC
|
||
|
|
controller.
|
||
|
|
Enable the respective DT node and specify the (always-on) regulator
|
||
|
|
and card-detect pin.
|
||
|
|
As a micro-SD slot does not feature a write-protect switch, we disable
|
||
|
|
this feature.
