* FocalTech FT6236 I2C touchscreen controller
Required properties:
- compatible : "focaltech,ft6236"
- reg : I2C slave address of the chip (0x38)
- interrupt-parent : a phandle pointing to the interrupt controller
serving the interrupt for this chip
- interrupts : interrupt specification for the touch controller
interrupt
- reset-gpios : GPIO specification for the RSTN input
- touchscreen-size-x : horizontal resolution of touchscreen (in pixels)
- touchscreen-size-y : vertical resolution of touchscreen (in pixels)
Optional properties:
- touchscreen-fuzz-x : horizontal noise value of the absolute input
device (in pixels)
- touchscreen-fuzz-y : vertical noise value of the absolute input
device (in pixels)
- touchscreen-inverted-x : X axis is inverted (boolean)
- touchscreen-inverted-y : Y axis is inverted (boolean)
- touchscreen-swapped-x-y: X and Y axis are swapped (boolean)
Swapping is done after inverting the axis
Example:
ft6x06@38 {
compatible = "focaltech,ft6236";
reg = <0x38>;
interrupt-parent = <&gpio>;
interrupts = <23 2>;
touchscreen-size-x = <320>;
touchscreen-size-y = <480>;
touchscreen-inverted-x;
touchscreen-swapped-x-y;
};
