trats2 uses gpf2-1 as the panel reset GPIO. gpy4-5 was only used on early revisions of the board.

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.
