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. arch/arm/boot/dts/imx6sl-evk.dts | 8 ++++++++ 1 file changed, 8 insertions(+)
