| ROCKCHIP USB2.0 PHY WITH INNO IP BLOCK |
| |
| Required properties (phy (parent) node): |
| - compatible : should be one of the listed compatibles: |
| * "rockchip,rk3328-usb2phy" |
| * "rockchip,rk3366-usb2phy" |
| * "rockchip,rk3399-usb2phy" |
| - reg : the address offset of grf for usb-phy configuration. |
| - #clock-cells : should be 0. |
| - clock-output-names : specify the 480m output clock name. |
| |
| Optional properties: |
| - clocks : phandle + phy specifier pair, for the input clock of phy. |
| - clock-names : input clock name of phy, must be "phyclk". |
| - assigned-clocks : phandle of usb 480m clock. |
| - assigned-clock-parents : parent of usb 480m clock, select between |
| usb-phy output 480m and xin24m. |
| Refer to clk/clock-bindings.txt for generic clock |
| consumer properties. |
| |
| Required nodes : a sub-node is required for each port the phy provides. |
| The sub-node name is used to identify host or otg port, |
| and shall be the following entries: |
| * "otg-port" : the name of otg port. |
| * "host-port" : the name of host port. |
| |
| 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: |
| * "otg-id" : for the otg id interrupt. |
| * "otg-bvalid" : for the otg vbus interrupt. |
| * "linestate" : for the host/otg linestate interrupt. |
| |
| Optional properties: |
| - phy-supply : phandle to a regulator that provides power to VBUS. |
| See ./phy-bindings.txt for details. |

| interrupt-names = "linestate"; |
| status = "okay"; |
| }; |
| }; |
