Documentation/devicetree/bindings/input/touchscreen/edt-ft5x06.txt

+FocalTech EDT-FT5x06 Polytouch driver
+=====================================
+
+There are 3 variants of the chip for various touch panel sizes
+FT5206GE1  2.8" .. 3.8"
+FT5306DE4  4.3" .. 7"
+FT5406EE8  7"   .. 8.9"
+
+The software interface is identical for all those chips, so that
+currently there is no need for the driver to distinguish between the
+different chips. Nevertheless distinct compatible strings are used so
+that a distinction can be added if necessary without changing the DT
+bindings.
+
+
+Required properties:
+ - compatible:  "edt,edt-ft5206"
+           or:  "edt,edt-ft5306"
+           or:  "edt,edt-ft5406"
+
+ - 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 touchdetect
+                     interrupt
+
+Optional properties:
+ - reset-gpios: GPIO specification for the RESET input
+ - wake-gpios:  GPIO specification for the WAKE input
+
+ - pinctrl-names: should be "default"
+ - pinctrl-0:   a phandle pointing to the pin settings for the
+                control gpios
+
+ - threshold:   allows setting the "click"-threshold in the range
+                from 20 to 80.
+
+ - gain:        allows setting the sensitivity in the range from 0 to
+                31. Note that lower values indicate higher
+                sensitivity.
+
+ - offset:      allows setting the edge compensation in the range from
+                0 to 31.
+
+Example:
+	polytouch: edt-ft5x06@38 {
+		compatible = "edt,edt-ft5406", "edt,edt-ft5x06";
+		reg = <0x38>;
+		pinctrl-names = "default";
+		pinctrl-0 = <&edt_ft5x06_pins>;
+		interrupt-parent = <&gpio2>;
+		interrupts = <5 0>;
+		reset-gpios = <&gpio2 6 1>;
+		wake-gpios = <&gpio4 9 0>;
+	};

Documentation/devicetree/bindings/input/touchscreen/zforce_ts.txt

+* Neonode infrared touchscreen controller
+
+Required properties:
+- compatible: must be "neonode,zforce"
+- reg: I2C address of the chip
+- interrupts: interrupt to which the chip is connected
+- gpios: gpios the chip is connected to
+  first one is the interrupt gpio and second one the reset gpio
+- x-size: horizontal resolution of touchscreen
+- y-size: vertical resolution of touchscreen
+
+Example:
+
+	i2c@00000000 {
+		/* ... */
+
+		zforce_ts@50 {
+			compatible = "neonode,zforce";
+			reg = <0x50>;
+			interrupts = <2 0>;
+
+			gpios = <&gpio5 6 0>, /* INT */
+				<&gpio5 9 0>; /* RST */
+
+			x-size = <800>;
+			y-size = <600>;
+		};
