1* Elan eKTF2127 I2C touchscreen controller
2
3Required properties:
4 - compatible : "elan,ektf2127"
5 - reg : I2C slave address of the chip (0x40)
6 - interrupt-parent : a phandle pointing to the interrupt controller
7 serving the interrupt for this chip
8 - interrupts : interrupt specification for the ektf2127 interrupt
9 - power-gpios : GPIO specification for the pin connected to the
10 ektf2127's wake input. This needs to be driven high
11 to take ektf2127 out of it's low power state

13For additional optional properties see: touchscreen.txt

17i2c@00000000 {
18 ektf2127: touchscreen@15 {
19 compatible = "elan,ektf2127";
20 reg = <0x15>;
21 interrupt-parent = <&pio>;
22 interrupts = <6 11 IRQ_TYPE_EDGE_FALLING>
23 power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>;
24 touchscreen-inverted-x;
25 touchscreen-swapped-x-y;
26 };
27};
