+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 = <®_vdd_tsp>;
+ vddo-supply = <&pm8916_l6>;
+ touchscreen-size-x = <540>;
+ touchscreen-size-y = <960>;
+ zinitix,mode = <2>;
+ };
+
+ /* ... */
+ };
