title: Socionext UniPhier USB3 High-Speed (HS) PHY
|
|
|
|
description: |
|
|
This describes the devicetree bindings for PHY interfaces built into
|
|
USB3 controller implemented on Socionext UniPhier SoCs.
|
|
Although the controller includes High-Speed PHY and Super-Speed PHY,
|
|
this describes about High-Speed PHY.
