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";
};
};
