[PATCH v3 6/9] ARM: dts: sama7g5: Add USB and UTMI DT nodes

[Sergiu Moga]

Define the USB and UTMI DT nodes for the sama7g5 SoC's. Since these have
not yet been defined in upstream Linux, place them in the U-Boot specific
DT file.

v1 -> v2:
- use usb@


v2 -> v3:
- place definitions in the U-Boot specific file and mention it in
the commit message
