* ROCKCHIP type-c PHY
---------------------
Required properties:
- compatible : must be "rockchip,rk3399-typec-phy"
- reg: Address and length of the usb phy control register set
- rockchip,grf : phandle to the syscon managing the "general
register files"
- clocks : phandle + clock specifier for the phy clocks
- clock-names : string, clock name, must be "tcpdcore", "tcpdphy-ref";
- assigned-clocks: main clock, should be <&cru SCLK_UPHY0_TCPDCORE> or
<&cru SCLK_UPHY1_TCPDCORE>;
- assigned-clock-rates : the phy core clk frequency, shall be: 50000000
- resets : a list of phandle + reset specifier pairs
- reset-names : string reset name, must be:
"uphy", "uphy-pipe", "uphy-tcphy"
Optional properties:
- extcon : extcon specifier for the Power Delivery
Required nodes : a sub-node is required for each port the phy provides.
The sub-node name is used to identify dp or usb3 port,
and shall be the following entries:
* "dp-port" : the name of DP port.
* "usb3-port" : the name of USB3 port.
Required properties (port (child) node):
- #phy-cells : must be 0, See ./phy-bindings.txt for details.
Deprecated properties, do not use in new device tree sources, these
properties are determined by the compatible value:
- rockchip,typec-conn-dir
- rockchip,usb3tousb2-en
- rockchip,external-psm
- rockchip,pipe-status
Example:
