Device tree bindings for HiSilicon INNO USB2 PHY |
|
|
|
Required properties: |
|
- compatible: Should be one of the following strings: |
|
"hisilicon,inno-usb2-phy", |
|
"hisilicon,hi3798cv200-usb2-phy". |
|
- reg: Should be the address space for PHY configuration register in peripheral |
|
controller, e.g. PERI_USB0 for USB 2.0 PHY01 on Hi3798CV200 SoC. |
|
- clocks: The phandle and clock specifier pair for INNO USB2 PHY device |
|
reference clock. |
|
- resets: The phandle and reset specifier pair for INNO USB2 PHY device reset |
|
signal. |
|
- #address-cells: Must be 1. |
|
- #size-cells: Must be 0. |
|
|
|
The INNO USB2 PHY device should be a child node of peripheral controller that |
|
contains the PHY configuration register, and each device suppports up to 2 PHY |
|
ports which are represented as child nodes of INNO USB2 PHY device. |
|
|
|
Required properties for PHY port node: |
|
- reg: The PHY port instance number. |
|
- #phy-cells: Defined by generic PHY bindings. Must be 0. |
|
- resets: The phandle and reset specifier pair for PHY port reset signal. |
|
|
|
Refer to phy/phy-bindings.txt for the generic PHY binding properties |
|
