+* FocalTech FT6236 I2C touchscreen controller
+
+Required properties:
+ - compatible            : "focaltech,ft6236"
+ - reg                   : I2C slave address of the chip (0x38)
+ - interrupt-parent      : a phandle pointing to the interrupt controller
+                           serving the interrupt for this chip
+ - interrupts            : interrupt specification for the touch controller
+                           interrupt
+ - reset-gpios           : GPIO specification for the RSTN input
+ - touchscreen-size-x    : horizontal resolution of touchscreen (in pixels)
+ - touchscreen-size-y    : vertical resolution of touchscreen (in pixels)
+
+Optional properties:
+ - touchscreen-fuzz-x    : horizontal noise value of the absolute input
+                           device (in pixels)
+ - touchscreen-fuzz-y    : vertical noise value of the absolute input
+                           device (in pixels)
+ - touchscreen-inverted-x : X axis is inverted (boolean)
+ - touchscreen-inverted-y : Y axis is inverted (boolean)
+ - touchscreen-swapped-x-y: X and Y axis are swapped (boolean)
+                           Swapping is done after inverting the axis
+
+Example:
+
+       ft6x06@38 {
+               compatible = "focaltech,ft6236";
+               reg = <0x38>;
+               interrupt-parent = <&gpio>;
+               interrupts = <23 2>;
+               touchscreen-size-x = <320>;
+               touchscreen-size-y = <480>;
+               touchscreen-inverted-x;
+               touchscreen-swapped-x-y;
+       };
