+ - 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

+		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>;
