Is this only needed for the panel itself and can you try to get the panel supplies set up correctly instead in that case please?

in the evb-schematics I see, vcc_lcd as supply for the panel. So I'd think the panel node here should have a power-supply = <&vcc_lcd>; instead of having the always-on above? Thanks Heiko
