* Elan eKTF2127 I2C touchscreen controller
Required properties:
- compatible : "elan,ektf2127" or "elan,ektf2132"
- 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 its 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;
touchscreen-swapped-x-y;
};
};
