The QMP Combo PHY is a dual-mode PHY
that can operate in either USB3 mode or DisplayPort mode. This
initial implementation focuses on USB3 mode to enable Super-Speed
USB support.
This is a port of the upstream Linux files to U-Boot:

Enabled and tested the driver on Qualcomm RB3 Gen2 (QCS6490) board.

Can you please do a follow-up to fix this tristate (and any other in

Sure Tom, will create a seperate patch to fix the tristates.
