Device tree bindings for Zinitx BT541 touchscreen controller
Required properties:
- compatible : Should be "zinitix,bt541"
- reg : I2C address of the chip. Should be 0x20
- interrupts : Interrupt to which the chip is connected
Optional properties:
- vdd-supply : Analog power supply regulator on VCCA pin
- vddo-supply : Digital power supply regulator on VDD pin
- zinitix,mode : Mode of reporting touch points. Some modes may not work
with a particular ts firmware for unknown reasons. Available
modes are 1 and 2. Mode 2 is the default and preferred.
The touchscreen-* properties are documented in touchscreen.txt in this
directory.
Example:
i2c@00000000 {
/* ... */
bt541@20 {
compatible = "zinitix,bt541";
reg = <0x20>;
interrupt-parent = <&msmgpio>;
interrupts = <13 IRQ_TYPE_EDGE_FALLING>;
pinctrl-names = "default";
pinctrl-0 = <&tsp_default>;
vdd-supply = <&reg_vdd_tsp>;
vddo-supply = <&pm8916_l6>;
touchscreen-size-x = <540>;
touchscreen-size-y = <960>;
zinitix,mode = <2>;
