Merge "input: touchscreen: bu21150-driver"

JDI bu21150 touch AFE controller

Required properties:

 - compatible			: should be "jdi,bu21150"

 - reg					: SPI address of the device

 - interrupt-parent		: parent of interrupt

 - interrupts			: interrupt of touch AFE

 - spi-max-frequency	: communication speed of the SPI

 - irq-gpio 			: irq gpio

 - rst-gpio				: reset gpio

 - power-supply			: type of power sequence

							Please use when adjusting the power sequence

Example:

	spi@f9966000 {

		jdi-bu21150@0 {

			compatible = "jdi,bu21150";

			reg = <0>;

			interrupt-parent = <&msmgpio>;

			interrupts = <61 0>;

			spi-max-frequency = <9600000>;

			irq-gpio = <&msmgpio 61 0>;

			rst-gpio = <&msmgpio 60 0>;

			power-supply = "apq8074-dragonboard";

		};

	};
