Note that this GPIO is shared with a switch, like on Salvator-X(S) and ULCB. As currently Linux cannot handle both, describing the LED precludes adding the switch later. (applies to the first 3 LEDs). > + led3 { > + gpios = <&gpio0 0 GPIO_ACTIVE_HIGH>; > + label = "LED3"; > + }; I cannot find LED3. According to the schematics GP0_0 == CS0n is used as the chipselect for the LVDS switch?
