trats2 uses gpf2-1 as the panel reset GPIO. gpy4-5 was only used on early revisions of the board. Fixes: 420ae8451a22 ("ARM: dts: exynos4412-trats2: add panel node") Signed-off-by: Simon Shields <simon@xxxxxxxxxxxxx>
Acked-by: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx> Tested-by: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx> It looks that this has been accidentally copy/pasted from the previous dts used for early version of the development board. I've checked the Trats2 schematic and indeed gpf2-1 is the correct pin for panel reset line.
