The Qualcomm PMI632 PMIC (found on Qualcomm Robotics RB2 platform)
doesn't support USB Power Delivery. However this PMIC still supports
handling of the Type-C port (orientation detection, etc). Reuse exiting
qcom-pmic-typec driver to support Type-C related functionality of this
PMIC. Use this to enable USB-C connector support on the RB2 platform.

Changes in v2:
- Split qcom_pmic_typec_pdphy_set_roles() changes to separate patch
  (Konrad)
- Simplified devm_kzalloc / sizeof() argument (Konrad)
- Made start / stop callbacks mandatory (Bryan)
- Reworked Type-C port handling into a backend similar to PD PHY (Bryan)
- Made more qcom-pmic-typec data static const (Bryan)
- Squashed usbc PHY single-lane removal patch (Konrad)
- Further usbc PHY cleanup (Konrad)
- Fixed order of DT properties in pmi632.dtsi (Konrad)
- Instead of specifying bogus PDOs for the port, specify pd-disable and
  typec-power-opmode properties for the connector
- Moved orientation-switch / usb-dual-role properties to sm6115.dtsi
  (Konrad)
- Linked usb_dwc3_ss and usb_qmpphy_usb_ss_in
- Link to v1: https://lore.kernel.org/r/20240113-pmi632-typec-v1-0-de7dfd459353@linaro.org

Hi Dmitry,

I'm happy to report that testing this series on v6.8-rc1 kernel on
sdm632-fairphone-fp3 shows that USB role switching is working with this!

It's not extensive testing but plugging in a USB stick and USB headphone
jack dongle in both directions show up in dmesg as expected, and
afterwards also USB networking gadget still works to ssh into the
device.

My .dts part is a bit different to your RB2 dts since
sdm632-fairphone-fp3 doesn't support USB 3.0, only USB 2.0, but
otherwise looks pretty similar. I'll send a patch for that once your
series has landed.

Not sure on which patches it makes sense, but have my:

Tested-by: Luca Weiss <luca.weiss@fairphone.com> # sdm632-fairphone-fp3

And for reference:

Only thing I've noticed here is "Host supports USB 3.0 SuperSpeed" which
is half true, to my knowledge SDM632 does support USB 3.0 but it's not
hooked up (for some reason) on most MSM8953/SDM632-based devices.
