Qualcomm's PM8941 USB ID Extcon device
Some Qualcomm PMICs have a "misc" module that can be used to detect when
the USB ID pin has been pulled low or high.
PROPERTIES
- compatible:
Usage: required
Value type: <string>
Definition: Should contain "qcom,pm8941-misc";
- reg:
Usage: required
Value type: <u32>
Definition: Should contain the offset to the misc address space
- interrupts:
Usage: required
Value type: <prop-encoded-array>
Definition: Should contain the usb id interrupt
- interrupt-names:
Usage: required
Value type: <stringlist>
Definition: Should contain the string "usb_id" for the usb id interrupt
Example:
pmic {
usb_id: misc@900 {
compatible = "qcom,pm8941-misc";
reg = <0x900>;
interrupts = <0x0 0x9 0 IRQ_TYPE_EDGE_BOTH>;
interrupt-names = "usb_id";
};
}
usb-controller {
extcon = <&usb_id>;
};
