-* 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)
-- 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@...00000 {
-
- /* ... */
-
- 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>;
- };
