- 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.
