1* FocalTech FT6236 I2C touchscreen controller
2
3Required properties:
4 - compatible : "focaltech,ft6236"
5 - reg : I2C slave address of the chip (0x38)
6 - interrupt-parent : a phandle pointing to the interrupt controller
7 serving the interrupt for this chip
8 - interrupts : interrupt specification for the touch controller
9 interrupt
10 - reset-gpios : GPIO specification for the RSTN input
11 - touchscreen-size-x : horizontal resolution of touchscreen (in pixels)
12 - touchscreen-size-y : vertical resolution of touchscreen (in pixels)
13
14Optional properties:
15 - touchscreen-fuzz-x : horizontal noise value of the absolute input
16 device (in pixels)
17 - touchscreen-fuzz-y : vertical noise value of the absolute input
18 device (in pixels)
19 - touchscreen-inverted-x : X axis is inverted (boolean)
20 - touchscreen-inverted-y : Y axis is inverted (boolean)
21 - touchscreen-swapped-x-y: X and Y axis are swapped (boolean)
22 Swapping is done after inverting the axis
23
24Example:
25
26 ft6x06@38 {
27 compatible = "focaltech,ft6236";
28 reg = <0x38>;
29 interrupt-parent = <&gpio>;
30 interrupts = <23 2>;
31 touchscreen-size-x = <320>;
32 touchscreen-size-y = <480>;
33 touchscreen-inverted-x;
34 touchscreen-swapped-x-y;
35 };
