From: Marco Frank <redacted>
It is preferred to use the panel compatible string rather than passing
the LCD timming in the device tree.
So pass the "sii,43wvf1g" compatible string, a new driver for the Seiko
Panel, which describes the parallel LCD.
This new driver needs two power supply, so pass 'dvdd-supply' and
'avdd-supply', which makes the kernel to turn on the LCD on is own.
Also, pass the 'backlight' property as described in
Documentation/devicetree/bindings/display/panel/simple-panel.txt
