* GSL 1680 touchscreen controller
Required properties:
- compatible : "silead,gsl1680"
- reg : I2C slave address of the chip (0x40)
- interrupt-parent : a phandle pointing to the interrupt controller
serving the interrupt for this chip
- interrupts : interrupt specification for the gsl1680 interrupt
- power-gpios : Specification for the pin connected to the gsl1680's
shutdown input. This needs to be driven high to take the
gsl1680 out of its low power state
- touchscreen-size-x : See touchscreen.txt
- touchscreen-size-y : See touchscreen.txt
Optional properties:
- touchscreen-inverted-x : See touchscreen.txt
- touchscreen-inverted-y : See touchscreen.txt
- touchscreen-swapped-x-y : See touchscreen.txt
- silead,max-fingers : maximum number of fingers the touchscreen can detect
Example:
i2c@00000000 {
gsl1680: touchscreen@40 {
compatible = "silead,gsl1680";
reg = <0x40>;
interrupt-parent = <&pio>;
interrupts = <6 11 IRQ_TYPE_EDGE_FALLING>;
power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>;
touchscreen-size-x = <480>;
touchscreen-size-y = <800>;
touchscreen-inverted-x;
touchscreen-swapped-x-y;
silead,max-fingers = <5>;
};
};
