+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.
