The eKTF2132 is a touchscreen controller found, for example, in the Kobo Aura ebook reader. It is similar to the ektf2127, but it uses a different packet type to report touch events.

* 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 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>;
