Subject: [PATCH v3 00/19] Enable Qualcomm QCS 404 HS/SS USB
Date: Wed, 22 Jan 2020 18:55:51 +0000	[thread overview]
Message-ID: <20200122185610.131930-1-bryan.odonoghue@linaro.org> (raw)

V1:
This series enables the Primary and Secondary USB controllers on the
QCS404, associated PHYs, role-switching and DTS descriptions.

The series takes in a number of patches worked on by a number of people
over the past few years from downstream, through to previous upstream
submissions for both of these interfaces. Additional work has been done to
enable USB role-switching.

1. USB SS
   - extcon has been dropped in favour of gpio-usb-conn as discussed and
     agreed previously by Jorge, Bjorn, Stephen Boyd and Jack Pham [1].

   - Regulator API has been updated following suggestions from Bjorn.
   
   - Sanitzation of the DT compatible name - dropped "snps" entirely
     from the name - it made almost no sense to me and doesn't appear
     consistent with similar naming conventions for Snopsys based IP.

2. USB HS
   - Regulator API changes here.
   - Dropped "snps" from the namespace for similar reasons as above.
   - Dropped "28nm" from the namespace, looked superfluous.
   - Changed "High-Speed" to "Hi-Speed".
   - [2]

3. DWC3 Role switching
   - At the time usb-gpio-conn was discussed it was mentioned that
     role-switching was absent from the DWC3 driver.
   - John Stultz has some patches in-flight for that, that I've included in
     this series for completeness.
   - Adds my SoB to relevant patches.
   - Drops gerrit ChangeId.

4. DWC3 usb-gpio-conn
   Needs to be a child node of the DWC3 driver so some code and DT binding
   is required for that.

5. QCOM-DWC3
   Since we are role-switching with an external PMIC supplying VBUS we want
   to skip past toggling VBUS from QCOM-DWC3 controlled registers, so a
   patch is added to the qcom-dwc3 driver to do that.
