Subject: [PATCH 05/10] dt-bindings: phy: Add documentation for Airoha AN7581
|
|
USB PHY
|
|
|
|
Add documentation for Airoha AN7581 USB PHY that describe the USB PHY
|
|
for the USB controller.
|
|
|
|
Airoha AN7581 SoC support a maximum of 2 USB port. The USB 2.0 mode is
|
|
always supported. The USB 3.0 mode is optional and depends on the Serdes
|
|
mode currently configured on the system for the USB port.
|
|
|
|
If the airoha,serdes-port property is not declared, it's assumed USB 3.0
|
|
mode is not supported, as the Serdes mode can't be validated.
