This set adds USB SS PHY support to Qualcomm's QCS404 SoC
The PHY is implemented using Synopsys SS PHY 1.0.0 IP
The code is losely based on Sriharsha Allenki's
<sallenki@xxxxxxxxxxxxxx> original implementation.
v2:
enable OTG mode detection
move vdd voltage levels to driver
use bulk_ control interfaces

[1] ss-phy-binding discussion:
- qcom,dwc3-ss-usb-phy exist for a generic usb2/usb3 phy driver that
was never merged. Rather than trying to re-use these bindings (or
delete them) I propose that we go ahead with the new separate
bindings for HS and SS: if not now - investigation in progress- in
the future it might be possible to have again a common phy driver
for which these old bindings would be the binding agreement.
