ROCKCHIP USB2.0 PHY WITH INNO IP BLOCK
|
|
|
|
Required properties (phy (parent) node):
|
|
- compatible : should be one of the listed compatibles:
|
|
* "rockchip,rk3228-usb2phy"
|
|
* "rockchip,rk3328-usb2phy"
|
|
* "rockchip,rk3366-usb2phy"
|
|
* "rockchip,rk3399-usb2phy"
|
|
* "rockchip,rv1108-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.
|
|
- rockchip,usbgrf : phandle to the syscon managing the "usb general
|
|
register files". When set driver will request its
|
|
phandle as one companion-grf for some special SoCs
|
|
(e.g RV1108).
|
|
|
|
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 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.
|
|
See ./phy-bindings.txt for details.
|
|
|
|
