Subject[PATCH V2] ARM: dts: imx6sl-evk: add missing GPIO iomux setting
Date
On i.MX6SL EVK board, the MX6SL_PAD_KEY_ROW5 pin is
used as lcd 3v3 regulator control pin, need to make
sure MX6SL_PAD_KEY_ROW5 is muxed as GPIO function
for controlling lcd 3v3 regulator.

Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

change since V1:
using a separate pin group for lcd regulator instead of putting gpio pin in hog group.
