on some Rockchip SoC (e.g RV1108).

@ -32,10 +32,14 @@ Required nodes : a sub-node is required for each port the phy provides.
Required properties (port (child) node):
- #phy-cells : must be 0. See ./phy-bindings.txt for details.
- interrupts : specify an interrupt for each entry in interrupt-names.
- interrupt-names : a list which shall be the following entries:
- interrupt-names : a list which should be one of the following cases:
Regular case:
* "otg-id" : for the otg id interrupt.
* "otg-bvalid" : for the otg vbus interrupt.
* "linestate" : for the host/otg linestate interrupt.
Some SoCs use one interrupt with the above muxed together, so for these
* "otg-mux" : otg-port interrupt, which mux otg-id/otg-bvalid/linestate
to one.
Optional properties:
- phy-supply : phandle to a regulator that provides power to VBUS.
