* Pixcir I2C touchscreen controllers
|
|
|
|
Required properties:
|
|
- compatible: must be "pixcir,pixcir_ts" or "pixcir,pixcir_tangoc"
|
|
- reg: I2C address of the chip
|
|
- interrupts: interrupt to which the chip is connected
|
|
- attb-gpio: GPIO connected to the ATTB line of the chip
|
|
- touchscreen-size-x: horizontal resolution of touchscreen (in pixels)
|
|
- touchscreen-size-y: vertical resolution of touchscreen (in pixels)
|
|
|
|
Optional properties:
|
|
- reset-gpios: GPIO connected to the RESET line of the chip
|
|
- enable-gpios: GPIO connected to the ENABLE line of the chip
|
|
- wake-gpios: GPIO connected to the WAKE line of the chip
|
|
|
|
Example:
|
|
|
|
i2c@00000000 {
|
|
/* ... */
|
|
|
|
pixcir_ts@5c {
|
|
compatible = "pixcir,pixcir_ts";
|
|
reg = <0x5c>;
|
|
interrupts = <2 0>;
|
|
attb-gpio = <&gpf 2 0 2>;
|
|
touchscreen-size-x = <800>;
|
|
touchscreen-size-y = <600>;
|
|
};
|
|
|
|
/* ... */
|
|
};
