+Microchip UCS1002 USB Port Power Controller
+
+Required properties:
+- compatible : Should be "microchip,ucs1002";
+- reg : I2C slave address
+
+Optional properties:
+- interrupts-extended : A list of interrupts lines present (could be either
+ corresponding to A_DET# pin, ALERT# pin, or both)
+- interrupt-names : A list of interrupt names. Should contain (if
+ present):
+ - "a_det" for line connected to A_DET# pin
+ - "alert" for line connected to ALERT# pin
+Example:
+
+&i2c3 {
+ charger@32 {
+ compatible = "microchip,ucs1002";
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_ucs1002_pins>;
+ reg = <0x32>;
+ interrupts-extended = <&gpio5 2 IRQ_TYPE_NONE>,
+ <&gpio3 21 IRQ_TYPE_NONE>;
+ interrupt-names = "a_det", "alert";
+ };
+};
