Subject: [PATCH v5 00/10] phy: qcom: Introduce USB support for SM8750

Add support for the PHYs and controllers used for USB on SM8750 SoCs.

---
Changes in v5:
- Removed refclk_src from the QMP PHY driver as that is no longer used.
- The decision to move the TCSR clkref property from controller --> phy
node was made in v4, and the refclk_src was a lingering change that was
meant to be removed.  CXO is the parent clock for TCSR clkref, so CXO
clk will be voted for as well.
- Relocate the SM8750 compatible within the qcom,dwc3 bindings.  This is
to take into account the change in clock list.
- Link to v4: https://lore.kernel.org/r/20250409-sm8750_usb_master-v4-0-6ec621c98be6@oss.qualcomm.com

Changes in v4:
- Made some fixups to the M31 eUSB2 driver
- Moved TCSR refclk_en to the QMP PHY DT node
- Link to v3: https://lore.kernel.org/r/20250324-sm8750_usb_master-v3-0-13e096dc88fd@quicinc.com

Changes in v3:
- Split platform DTs into separate commits.
- Fixed up M31 eUSB2 PHY driver with feedback received.
- Reordered DT properties based on feedback.
- Rewrote commit message for enabling EUSB driver.
- Link to v2: https://lore.kernel.org/r/20250304-sm8750_usb_master-v2-0-a698a2e68e06@quicinc.com

Changes in v2:
- Added new QMP PHY register definitions for v8 based QMP phys.
- Made changes to clean up some code in the M31 eUSB2 PHY driver based
on feedback received.
- Added bulk regulator operations in M31 eUSB2 PHY, to ensure that
both the vdd and vdda12 regulators are properly voted for.
- Removed external references to other dt bindings in M31 example for
the DT bindings change.
- Split DT patches between SoC and plaform changes, as well as the
PHY subsystem Kconfig changes when introducing the M31 eUSB2 PHY.
- Added orientation switch and port definitions in the DT changes.EDITME: describe what is new in this series revision.
- Link to v1: https://lore.kernel.org/r/20250113-sm8750_usb_master-v1-0-09afe1dc2524@quicinc.com
