ST STiH407 USB PHY controller
This file documents the dt bindings for the usb picoPHY driver which is the PHY for both USB2 and USB3
host controllers (when controlling usb2/1.1 devices) available on STiH407 SoC family from STMicroelectronics.
Required properties:
- compatible : should be "st,stih407-usb2-phy"
- reg : contain the offset and length of the system configuration registers
used as glue logic to control & parameter phy
- reg-names : the names of the system configuration registers in "reg", should be "param" and "reg"
- st,syscfg : sysconfig register to manage phy parameter at driver level
- resets : list of phandle and reset specifier pairs. There should be two entries, one
for the whole phy and one for the port
- reset-names : list of reset signal names. Should be "global" and "port"
See: Documentation/devicetree/bindings/reset/st,sti-powerdown.txt
See: Documentation/devicetree/bindings/reset/reset.txt
Example:
usb2_picophy0: usbpicophy@f8 {
compatible = "st,stih407-usb2-phy";
reg = <0xf8 0x04>, /* syscfg 5062 */
<0xf4 0x04>; /* syscfg 5061 */
reg-names = "param", "ctrl";
#phy-cells = <0>;
st,syscfg = <&syscfg_core>;
resets = <&softreset STIH407_PICOPHY_SOFTRESET>,
<&picophyreset STIH407_PICOPHY0_RESET>;
reset-names = "global", "port";

STMicroelectronics STiH41x USB PHY binding
------------------------------------------
This file contains documentation for the usb phy found in STiH415/6 SoCs from
STMicroelectronics.
Required properties:
- compatible : should be "st,stih416-usb-phy" or "st,stih415-usb-phy"
- st,syscfg : should be a phandle of the syscfg node
- clock-names : must contain "osc_phy"
- clocks : must contain an entry for each name in clock-names.
See: Documentation/devicetree/bindings/clock/clock-bindings.txt
- #phy-cells : must be 0 for this phy
See: Documentation/devicetree/bindings/phy/phy-bindings.txt
Example:
usb2_phy: usb2phy@0 {
compatible = "st,stih416-usb-phy";
#phy-cell = <0>;
st,syscfg = <&syscfg_rear>;
clocks = <&clk_sysin>;

* Renesas R-Car generation 2 USB PHY
This file provides information on what the device node for the R-Car generation
2 USB PHY contains.
Required properties:
- compatible: "renesas,usb-phy-r8a7790" if the device is a part of R8A7790 SoC.
"renesas,usb-phy-r8a7791" if the device is a part of R8A7791 SoC.
- reg: offset and length of the register block.
- #address-cells: number of address cells for the USB channel subnodes, must
be <1>.
- #size-cells: number of size cells for the USB channel subnodes, must be <0>.
- clocks: clock phandle and specifier pair.
- clock-names: string, clock input name, must be "usbhs".
The USB PHY device tree node should have the subnodes corresponding to the USB
channels. These subnodes must contain the following properties:
- reg: the USB controller selector; see the table below for the values.
- #phy-cells: see phy-bindings.txt in the same directory, must be <1>.
The phandle's argument in the PHY specifier is the USB controller selector for
the USB channel; see the selector meanings below:
+-----------+---------------+---------------+
|\ Selector | | |
+ --------- + 0 | 1 |
| Channel \| | |
+-----------+---------------+---------------+
| 0 | PCI EHCI/OHCI | HS-USB |
| 2 | PCI EHCI/OHCI | xHCI |
+-----------+---------------+---------------+
Example (Lager board):
usb-phy@e6590100 {
compatible = "renesas,usb-phy-r8a7790";
reg = <0 0xe6590100 0 0x100>;
#address-cells = <1>;
#size-cells = <0>;
clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
clock-names = "usbhs";
usb-channel@0 {
reg = <0>;
#phy-cells = <1>;
};
usb-channel@2 {
reg = <2>;
#phy-cells = <1>;
};
};
