ARM: davinci: da850: add mmc DT entries (88df4122) · Commits · 戴 / test

Add DT entry for MMC. Also add entry for pinmux information. Tested: 1) Without GPIO card detection and EDMA support as DT support for GPIO and EDMA are yet come. 2) By creating/deleting files and mounting/unmounting the partition. Signed-off-by:
