		PixArt pat9125 rotating switch

		The Pixart's PAT9125 controller is connected to the host processor via I2C.
		It detects the rotation when user rotates the switch and generates interrupt
		to the Host processor. The host processor reads the direction and number of
		steps over I2C and passes the data to the rest of the system.

		Required properties:
		- compatible : should be "pixart,pat9125".
		- reg : i2c slave address of the device.
		- interrupt-parent : parent of interrupt.
		- interrupts : interrupt to indicate motion of the rotating switch.

		Optional properties:
		- pixart,inverse-x : boolean, use this to invert the x data before sending it to input
		framework.
		- pixart,inverse-y : boolean, use this to invert the y data before sending it to input
		framework.
		- pixart,press-enabled : boolean, use this to enable detection of pressing the button.

		Required properties if 'pixart,press-enabled' DT property is defined:
		- pixart,press-keycode : keycode to be sent when press is detected by the driver.

		Example:
		pixart_pat9125@75 {
		compatible = "pixart,pat9125";
		reg = <0x75>;
		interrupt-parent = <&msm_gpio>;
		interrupts = <98 0x2008>;
		pixart,irq-gpio = <&msm_gpio 98 0x2008>;
		};

		Say Y to enable support for the PixArt OTS pat9125
		rotating switch driver.
		If unsure, say N.

		To compile this driver as a module, choose M here: the
