1ROCKCHIP USB2.0 PHY WITH INNO IP BLOCK
2
3Required properties (phy (parent) node):
4 - compatible : should be one of the listed compatibles:
5 * "rockchip,rk3228-usb2phy"
6 * "rockchip,rk3328-usb2phy"
7 * "rockchip,rk3366-usb2phy"
8 * "rockchip,rk3399-usb2phy"
9 * "rockchip,rv1108-usb2phy"
10 - reg : the address offset of grf for usb-phy configuration.
11 - #clock-cells : should be 0.
12 - clock-output-names : specify the 480m output clock name.
13
14Optional properties:
15 - clocks : phandle + phy specifier pair, for the input clock of phy.
16 - clock-names : input clock name of phy, must be "phyclk".
17 - assigned-clocks : phandle of usb 480m clock.
18 - assigned-clock-parents : parent of usb 480m clock, select between
19 usb-phy output 480m and xin24m.
20 Refer to clk/clock-bindings.txt for generic clock
21 consumer properties.
22 - rockchip,usbgrf : phandle to the syscon managing the "usb general
23 register files". When set driver will request its
24 phandle as one companion-grf for some special SoCs
25 (e.g RV1108).
26 - extcon : phandle to the extcon device providing the cable state for
27 the otg phy.
28
29Required nodes : a sub-node is required for each port the phy provides.
30 The sub-node name is used to identify host or otg port,
31 and shall be the following entries:
32 * "otg-port" : the name of otg port.
33 * "host-port" : the name of host port.
34
35Required properties (port (child) node):
36 - #phy-cells : must be 0. See ./phy-bindings.txt for details.
37 - interrupts : specify an interrupt for each entry in interrupt-names.
38 - interrupt-names : a list which should be one of the following cases:
39 Regular case:
40 * "otg-id" : for the otg id interrupt.
41 * "otg-bvalid" : for the otg vbus interrupt.
42 * "linestate" : for the host/otg linestate interrupt.
43 Some SoCs use one interrupt with the above muxed together, so for these
44 * "otg-mux" : otg-port interrupt, which mux otg-id/otg-bvalid/linestate
45 to one.
46
47Optional properties:
48 - phy-supply : phandle to a regulator that provides power to VBUS.
49 See ./phy-bindings.txt for details.
