+* D-Link DIR-685 Touchkeys
+
+This is a I2C one-off touchkey controller based on the Cypress Semiconductor
+CY8C214 MCU with some firmware in its internal 8KB flash. The circuit
+board inside the router is named E119921.
+
+The touchkey device node should be placed inside an I2C bus node.
+
+Required properties:
+- compatible: must be "dlink,dir685-touchkeys"
+- reg: the I2C address of the touchkeys
+- interrupts: reference to the interrupt number
+
+Example:
+
+touchkeys@26 {
+ compatible = "dlink,dir685-touchkeys";
+ reg = <0x26>;
+ interrupt-parent = <&gpio0>;
+ interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
+};

+* ST-Microelectronics FingerTip touchscreen controller
+
+The ST-Microelectronics FingerTip device provides a basic touchscreen
+functionality. Along with it the user can enable the touchkey which can work as
+a basic HOME and BACK key for phones.
+
+The driver supports also hovering as an absolute single touch event with x, y, z
+coordinates.
+
+Required properties:
+- compatible : must be "st,stmfts"
+- reg : I2C slave address, (e.g. 0x49)
+- interrupt-parent : the phandle to the interrupt controller which provides
+ the interrupt
+- interrupts : interrupt specification
+- avdd-supply : analogic power supply
+- vdd-supply : power supply
+- touchscreen-size-x : see touchscreen.txt
+- touchscreen-size-y : see touchscreen.txt
+
+Optional properties:
+- touch-key-connected : specifies whether the touchkey feature is connected
+- ledvdd-supply : power supply to the touch key leds
+
+Example:
+
+i2c@00000000 {
+
+ /* ... */
+
+ touchscreen@49 {
+ compatible = "st,stmfts";
+ reg = <0x49>;
+ interrupt-parent = <&gpa1>;
+ interrupts = <1 IRQ_TYPE_NONE>;
+ touchscreen-size-x = <1599>;
+ touchscreen-size-y = <2559>;
+ touch-key-connected;
+ avdd-supply = <&ldo30_reg>;
+ vdd-supply = <&ldo31_reg>;
+ ledvdd-supply = <&ldo33_reg>;
+ };
