Whenever you add a board DTS support, please also add the DTB target
into arch/arm/boot/dts/Makefile.

Please use the macros in include/dt-bindings/gpio/gpio.h to get a better
readability.

Please follow the way that most IMX dts files do, i.e.

	regulators {
		reg_3p3v: regulator at 0 {
			reg = <0>;
		};
	};
