-Microchip UCS1002 USB Port Power Controller
-
-Required properties:
-- compatible		: Should be "microchip,ucs1002";
-- reg			: I2C slave address
-
-Optional properties:
-- interrupts		: 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
-			  Both are expected to be IRQ_TYPE_EDGE_BOTH
-Example:
-
-&i2c3 {
-	charger@32 {
-		compatible = "microchip,ucs1002";
-		pinctrl-names = "default";
-		pinctrl-0 = <&pinctrl_ucs1002_pins>;
-		reg = <0x32>;
-		interrupts-extended = <&gpio5 2 IRQ_TYPE_EDGE_BOTH>,
-				      <&gpio3 21 IRQ_TYPE_EDGE_BOTH>;
-		interrupt-names = "a_det", "alert";
-	};
-};
