| 2 | |
| 3 | This file documents the dt bindings for the usb picoPHY driver which is the PHY for both USB2 and USB3 |
| 4 | host controllers (when controlling usb2/1.1 devices) available on STiH407 SoC family from STMicroelectronics. |
| 5 | |
| 6 | Required properties: |
| 7 | - compatible : should be "st,stih407-usb2-phy" |
| 8 | - st,syscfg : phandle of sysconfig bank plus integer array containing phyparam and phyctrl register offsets |
| 9 | - resets : list of phandle and reset specifier pairs. There should be two entries, one |
| 10 | for the whole phy and one for the port |
| 11 | - reset-names : list of reset signal names. Should be "global" and "port" |

| 15 | Example: |
| 16 | |
| 17 | usb2_picophy0: usbpicophy { |
| 18 | compatible = "st,stih407-usb2-phy"; |
| 19 | #phy-cells = <0>; |
| 20 | st,syscfg = <&syscfg_core 0x100 0xf4>; |
| 21 | resets = <&softreset STIH407_PICOPHY_SOFTRESET>, |
| 22 | <&picophyreset STIH407_PICOPHY0_RESET>; |
| 23 | reset-names = "global", "port"; |
| 24 | }; |
