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 superflous.
- Changed "High-Speed" to "Hi-Speed".

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.
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.
6. DWC3 USB Role Switching
- Includes some patches in-flight from John Stultz.
- Adds my SoB to relevant patches.
- Drops gerrit ChangeId.
