| |
It is preferred to use the panel compatible string rather than passing the LCD timing in the device tree.
So pass the "sii,43wvf1g" compatible string which describes the parallel LCD.
Also, pass the 'backlight' property as described in Documentation/devicetree/bindings/display/panel/simple-panel.txt
