+FocalTech touch controller
+
+The focaltech controller is connected to host processor via i2c.
+The controller generates interrupts when the user touches the panel.
+The host controller is expected to read the touch coordinates over
+i2c and pass the coordinates to the rest of the system.
+
+Required properties:
+ - compatible		: should be "focaltech,fts"
+ - reg			: i2c slave address of the device, should be <0x38>
+ - interrupt-parent	: parent of interrupt
+ - interrupts		: irq gpio, "0x02" stands for that the irq triggered by falling edge.
+ - focaltech,irq-gpio	: irq gpio, same as "interrupts" node.
+ - focaltech,reset-gpio	: reset gpio
+ - focaltech,num-max-touches	: maximum number of touches support
+ - focaltech,display-coords	: display resolution in pixels. A four tuple consisting of minX, minY, maxX and maxY.
+
+Optional properties:
+ - focaltech,have-key		: specify if virtual keys are supported
+ - focaltech,key-number		: number of keys
+ - focaltech,keys		: virtual key codes mapping to the coords
+ - focaltech,key-y-coord	: constant y coordinate of keys, depends on the y resolution
+ - focaltech,key-x-coords	: constant x coordinates of keys, depends on the x resolution
+ - focaltech,swap-xy		: swap x-y coordinates
+ - focaltech,panel-type		: set panel type, default is FT5416 panel
+ - focaltech,scaling-down-half	: scale down the x-y coordiantes to half
+
+
+Example:
+	i2c@f9927000 {
+		focaltech@38{
+			compatible = "focaltech,fts";
+			reg = <0x38>;
+			interrupt-parent = <&msm_gpio>;
+			interrupts = <13 0x02>;
+			focaltech,reset-gpio = <&msm_gpio 12 0x01>;
+			focaltech,irq-gpio = <&msm_gpio 13 0x02>;
+			focaltech,max-touch-number = <5>;
+			focaltech,display-coords =  <0 0 1080 1920>;
+
+			focaltech,have-key;
+			focaltech,key-number = <3>;
+			focaltech,keys = <139 102 158>;
+			focaltech,key-y-coord = <2000>;
+			focaltech,key-x-coords = <200 600 800>;
+			focaltech,swap-xy;
+		};
+	};
