* Elan eKTF2127 I2C touchscreen controller
|
|
Required properties:
|
- compatible : "elan,ektf2127"
|
- reg : I2C slave address of the chip (0x40)
|
- interrupts : interrupt specification for the ektf2127 interrupt
|
- power-gpios : GPIO specification for the pin connected to the
|
ektf2127's wake input. This needs to be driven high
|
to take ektf2127 out of it's low power state
|
|
For additional optional properties see: touchscreen.txt

Example:
|
|
i2c@00000000 {
|
ektf2127: touchscreen@15 {
|
compatible = "elan,ektf2127";
|
reg = <0x15>;
|
interrupt-parent = <&pio>;
|
interrupts = <6 11 IRQ_TYPE_EDGE_FALLING>
|
power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>;
|
touchscreen-inverted-x;
