[PATCH v6 0/4] Add USB Phy driver and binding changes for Qualcomm Shikra SoC

[Krishna Kurapati]

This series adds Driver and binding changes for USB Phys on Shikra.
There are two USB controllers - One of them is SS capable and other is
highspeed only capable.

Changes in v6:
- Fix the minItems and maxItems for reset-names in qmp phy yaml

Link to v5:
https://lore.kernel.org/all/20260711-shikra-usbphy-v5-v5-0-229ba3602737@oss.qualcomm.com/

Changes in v5:
- Fixed shikra specific minItems property for qmp bindings
- Rebased qusb2 driver changes on top of Dmitry's change [1]

Link to v4:
https://lore.kernel.org/all/20260701165051.4122259-1-krishna.kurapati@oss.qualcomm.com/

Changes in v4:
- Moved to using qcs615-usb3-dp-phy and added resets specific to shikra
- Updated bindings to reflect that there are 3 resets used in qmp phy
- Add remote endpoints and orientation-switch for Type-c handling

Link to v3:
https://lore.kernel.org/all/20260526184401.3959717-1-pratham.pratap@oss.qualcomm.com/

Changes in v3:
- Moved to using qcs615-usb3-dp-phy since the DP Phy is present although
not operational.
- Using Talos as a fallback for shikra in qmp driver
- Add required "phy" reset in qmp usbc driver since its needed on Shikra

Link to v2:
https://lore.kernel.org/all/20260504170659.282532-1-krishna.kurapati@oss.qualcomm.com/

Changes in v2:
- Separated the usb controller binding changes
- Updated commit texts.

[PATCH v6 2/4] dt-bindings: phy: qcs615-qmp-usb3dp: Add support for Shikra SoC

[Krishna Kurapati]

Declare the USB-C QMP PHY present on the Qualcomm Shikra SoC. Shikra uses
3 resets to be programmed before initialising the phy. As per the hardware
documentation, the third reset is PHY_PRIM_SP0_BCR, hence naming it "phy".

Also, add remote endpoints and orientation switch support for getting
Type-C orientation information.

[PATCH v6 3/4] phy: qcom-qusb2: Add support for Shikra

[Krishna Kurapati]

Add init sequence and phy configuration for Shikra. Since the init
sequence is same as that of QCS615, reuse the existing init table in
Shikra.
