Kishon writes:

phy: for 4.9 (with extcon merge resolution)

updated tag for 4.9 based on usb-next along with extcon merge
resolution

phy updates includes:
*) phy driver for USB 3.0 PHY on Northstar
*) phy driver for Rockchip usb2phy
*) phy driver for the Rockchip SoC internal PCIe PHY
*) phy driver for USB Type-C PHY on rk3399
*) phy_reset() API
*) support for Allwinner A64 usb phy, usb2 phy in r8a7796
*) Fixes in twl4030-usb, tegra phy, sun4i-usb phy, da8xx-usb phy
   and omap-usb2 phy
*) other misc cleanups

Driver for Broadcom Northstar USB 3.0 PHY



Required properties:



- compatible: one of: "brcm,ns-ax-usb3-phy", "brcm,ns-bx-usb3-phy".

- reg: register mappings for DMP (Device Management Plugin) and ChipCommon B

       MMI.

- reg-names: "dmp" and "ccb-mii"



Initialization of USB 3.0 PHY depends on Northstar version. There are currently

three known series: Ax, Bx and Cx.

Known A0: BCM4707 rev 0

Known B0: BCM4707 rev 4, BCM53573 rev 2

Known B1: BCM4707 rev 6

Known C0: BCM47094 rev 0



Example:

	usb3-phy {

		compatible = "brcm,ns-ax-usb3-phy";

		reg = <0x18105000 0x1000>, <0x18003000 0x1000>;

		reg-names = "dmp", "ccb-mii";

		#phy-cells = <0>;

	};

ROCKCHIP USB2.0 PHY WITH INNO IP BLOCK



Required properties (phy (parent) node):

 - compatible : should be one of the listed compatibles:

	* "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".



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.



Example:



grf: syscon@ff770000 {

	compatible = "rockchip,rk3366-grf", "syscon", "simple-mfd";

	#address-cells = <1>;

	#size-cells = <1>;



...



	u2phy: usb2-phy@700 {

		reg = <0x700 0x2c>;

		#clock-cells = <0>;

		clock-output-names = "sclk_otgphy0_480m";

* 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"

 - resets : a list of phandle + reset specifier pairs

 - reset-names : string reset name, must be:

		 "uphy", "uphy-pipe", "uphy-tcphy"

 - extcon : extcon specifier for the Power Delivery



Note, there are 2 type-c phys for RK3399, and they are almost identical, except

these registers(description below), every register node contains 3 sections:

offset, enable bit, write mask bit.

 - rockchip,typec-conn-dir : the register of type-c connector direction,

   for type-c phy0, it must be <0xe580 0 16>;

   for type-c phy1, it must be <0xe58c 0 16>;

 - rockchip,usb3tousb2-en : the register of type-c force usb3 to usb2 enable

   control.

   for type-c phy0, it must be <0xe580 3 19>;

   for type-c phy1, it must be <0xe58c 3 19>;

 - rockchip,external-psm : the register of type-c phy external psm clock

   selection.

   for type-c phy0, it must be <0xe588 14 30>;

   for type-c phy1, it must be <0xe594 14 30>;

 - rockchip,pipe-status : the register of type-c phy pipe status.

   for type-c phy0, it must be <0xe5c0 0 0>;

   for type-c phy1, it must be <0xe5c0 16 16>;



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.
