Bindings, specific for the sh_mobile_ceu_camera.c driver:
 - compatible: Should be "renesas,sh-mobile-ceu"
 - reg: register base and size
 - interrupts: the interrupt number
 - interrupt-parent: the interrupt controller
 - renesas,max-width: maximum image width, supported on this SoC
 - renesas,max-height: maximum image height, supported on this SoC

Example:

ceu0: ceu@fe910000 {
	compatible = "renesas,sh-mobile-ceu";
	reg = <0xfe910000 0xa0>;
	interrupt-parent = <&intcs>;
	interrupts = <0x880>;
	renesas,max-width = <8188>;
	renesas,max-height = <8188>;
};
