This set adds USB SS PHY support to Qualcomm's QCS404 SoC
The PHY is implemented using Synopsys' SS PHY IP

The code is losely based on Sriharsha Allenki's
<sallenki@codeaurora.org> original implementation.

v2:
  enable OTG mode detection
  move vdd voltage levels to driver
  use bulk_ control interfaces
  ss-phy-bindings [1]

v3:
  remove clk/regulator counters
  vdd constrains in device tree
  update error labels
  fix get_optional vbus
  allocate arrays statically
  fix typos in bindings

[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.
