Prior to adding dt-bindings for SoC-dependent controllers, rename the phy nodes and their parent nodes to the generic names in the example. And drop parent nodes of each phy as they are not directly necessary here.

|

|
|
description: |
|
|
This describes the devicetree bindings for PHY interface built into
|
|
USB2 controller implemented on Socionext UniPhier SoCs.
|
|
Pro4 SoC has both USB2 and USB3 host controllers, however, this USB3
|
|
controller doesn't include its own High-Speed PHY. This needs to specify
|
|
USB2 PHY instead of USB3 HS-PHY.
