Bindings for EETI touchscreen controller
|
|
|
|
Required properties:
|
|
- compatible: should be "eeti,exc3000-i2c"
|
|
- reg: I2C address of the chip. Should be set to <0xa>
|
|
- interrupts: interrupt to which the chip is connected
|
|
|
|
Optional properties:
|
|
- attn-gpios: A handle to a GPIO to check whether interrupt is still
|
|
latched. This is necessary for platforms that lack
|
|
support for level-triggered IRQs.
|
|
|
|
The following optional properties described in touchscreen.txt are
|
|
also supported:
|
|
|
|
- touchscreen-inverted-x
|
|
- touchscreen-inverted-y
|
|
- touchscreen-swapped-x-y
|
|
|
|
Example:
|
|
|
|
i2c-master {
|
|
touchscreen@a {
|
|
compatible = "eeti,exc3000-i2c";
|
|
reg = <0xa>;
|
|
interrupt-parent = <&gpio>;
|
|
interrupts = <123 IRQ_TYPE_EDGE_RISING>;
|
|
attn-gpios = <&gpio 123 GPIO_ACTIVE_HIGH>;
|
|
};
|
|
};
