Subject: [PATCH v4 0/4] USB SS PHY for Qualcomm's QCS404
Date: Thu,  7 Feb 2019 12:17:30 +0100	[thread overview]
Message-ID: <20190207111734.24171-1-jorge.ramirez-ortiz@linaro.org> (raw)

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

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
