[RFC PATCH 5/5] arm64: dts: sunxi: add MMC nodes to Pine64 and BPi-M64 .dts

From: Andre Przywara
Date: Tue Aug 09 2016 - 07:52:20 EST


Those two boards connect a microSD card slot to the MMC0 controller.
Add the dummy regulator and enable MMC0 to allow accessing the SD card.

The BananaPi M64 has an on-board eMMC chip connected to the MMC2
controller, but the existing MMC driver does not support this properly
yet, so keep this one disabled for now.
