1 FocalTech EDT-FT5x06 Polytouch driver
2 =====================================
4 There are 3 variants of the chip for various touch panel sizes
9 The software interface is identical for all those chips, so that
10 currently there is no need for the driver to distinguish between the
11 different chips. Nevertheless distinct compatible strings are used so
12 that a distinction can be added if necessary without changing the DT
17 - compatible: "edt,edt-ft5206"
21 - reg: I2C slave address of the chip (0x38)
22 - interrupt-parent: a phandle pointing to the interrupt controller
23 serving the interrupt for this chip
24 - interrupts: interrupt specification for the touchdetect
28 - reset-gpios: GPIO specification for the RESET input
29 - wake-gpios: GPIO specification for the WAKE input
31 - pinctrl-names: should be "default"
32 - pinctrl-0: a phandle pointing to the pin settings for the
35 - threshold: allows setting the "click"-threshold in the range
38 - gain: allows setting the sensitivity in the range from 0 to
39 31. Note that lower values indicate higher
42 - offset: allows setting the edge compensation in the range from
