Thanks for the information. You're correct; I'll add the two suggested properties, XRESET and VDD, to the binding. I'll also implement the XRESET handling in the driver. I missed the XRESET pin because my testing setup was working without it. For VDD, it's currently connected to the RPi's 5V output. While other Sitronix display bindings in the kernel don't currently define a supply property (running "git grep -i supply Documentation/devicetree/bindings/display/sitronix*" confirmed this), I agree it should be included for a complete binding. I'll define it as a fixed-regulator in my display DT node. > > > Best regards, > Krzysztof
