* EETI eGalax Multiple Touch Controller
|
|
|
|
Required properties:
|
|
- compatible: must be "eeti,egalax_ts"
|
|
- reg: i2c slave address
|
|
- interrupts: touch controller interrupt
|
|
- wakeup-gpios: the gpio pin to be used for waking up the controller
|
|
and also used as irq pin
|
|
|
|
Example:
|
|
|
|
touchscreen@4 {
|
|
compatible = "eeti,egalax_ts";
|
|
reg = <0x04>;
|
|
interrupt-parent = <&gpio1>;
|
|
interrupts = <9 IRQ_TYPE_LEVEL_LOW>;
|
|
wakeup-gpios = <&gpio1 9 GPIO_ACTIVE_LOW>;
|
|
};
