		- lcd-supply: Regulator for LCD supply voltage.
		- fsl,dmacr: DMA Control Register value. This is optional. By default, the
		register is not modified as recommended by the datasheet.
		- fsl,lpccr: Contrast Control Register value. This property provides the
		default value for the contrast control register.
		If that property is ommited, the register is zeroed.
