-* 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:
- tcphy0: phy@ff7c0000 {
- compatible = "rockchip,rk3399-typec-phy";
- reg = <0x0 0xff7c0000 0x0 0x40000>;
- rockchip,grf = <&grf>;
- extcon = <&fusb0>;
- clocks = <&cru SCLK_UPHY0_TCPDCORE>,
- <&cru SCLK_UPHY0_TCPDPHY_REF>;
- clock-names = "tcpdcore", "tcpdphy-ref";
- assigned-clocks = <&cru SCLK_UPHY0_TCPDCORE>;
- assigned-clock-rates = <50000000>;
- resets = <&cru SRST_UPHY0>,
- <&cru SRST_UPHY0_PIPE_L00>,
- <&cru SRST_P_UPHY0_TCPHY>;
- reset-names = "uphy", "uphy-pipe", "uphy-tcphy";
-
- tcphy0_dp: dp-port {
- #phy-cells = <0>;
- };
-
- tcphy0_usb3: usb3-port {
- #phy-cells = <0>;
- };
- };
-
- tcphy1: phy@ff800000 {
- compatible = "rockchip,rk3399-typec-phy";
- reg = <0x0 0xff800000 0x0 0x40000>;
- rockchip,grf = <&grf>;
- extcon = <&fusb1>;
- clocks = <&cru SCLK_UPHY1_TCPDCORE>,
- <&cru SCLK_UPHY1_TCPDPHY_REF>;
- clock-names = "tcpdcore", "tcpdphy-ref";
- assigned-clocks = <&cru SCLK_UPHY1_TCPDCORE>;
- assigned-clock-rates = <50000000>;
- resets = <&cru SRST_UPHY1>,
- <&cru SRST_UPHY1_PIPE_L00>,
- <&cru SRST_P_UPHY1_TCPHY>;
- reset-names = "uphy", "uphy-pipe", "uphy-tcphy";
-
- tcphy1_dp: dp-port {
- #phy-cells = <0>;
- };
-
- tcphy1_usb3: usb3-port {

- };

properties:
Convert the Rockchip RK3399 Type-C PHY to DT schema format. Add the missing "power-domains" property and "port" and "orientation-switch" properties in the child nodes. Omit the previously deprecated properties as they aren't used anywhere. Drop the 2nd example which was pretty much identical to the 1st example.
