Subject: [PATCH v4 0/4] USB SS PHY for Qualcomm's QCS404

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@...eaurora.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

v4:
 dts:
   make compatible tag more specific to the driver
   define a connector node to contain the vbus regulator
   fix the resets definition
   fix example node
   remove unused binding (qcom-dwc3-usb-phy)
   connector: add optional property vbus-supply
 driver:
   vbus regulator is no longer optional
   
[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 I chose
 to delete them for simplicity
 

Jorge Ramirez-Ortiz (4):
  dt-bindings: phy: remove qcom-dwc3-usb-phy
  dt-bindings: connector: Add vbus-supply property
  dt-bindings: Add Qualcomm USB SuperSpeed PHY bindings
  phy: qualcomm: usb: Add SuperSpeed PHY driver
