From 64edbcdd9c8d2aac36bead7f8cdafe0ec02bab40 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Thu, 28 Jun 2012 11:45:01 +0800 Subject: [PATCH] ARM: dts: imx28-evk: add vmmc-supply for mmc device Add vmmc-supply for mmc device, so that the power to mmc slot can be turned on by mmc driver if bootloader hasn't done it. Also remove "okay" status for mmc1/ssp1, as the device has pin conflict with gpmi-nand. Actually the device is already disabled since the mxs-mmc driver adopts pinctrl support because there is no pinctrl setup for the device in dts. Make this explicit by removing "okay" status.
