* 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>;
};
};
