Subject: [PATCH v6 0/8] Introduce Glymur USB support

This series enables the PHY level changes that are required to support
the type C based controllers and the multiport controller.  The typeC
ports utilize a usb43dp based QMP PHY for the SSUSB path, while using
the M31 eUSB2 PHY for the HSUSB path.  For the multiport controller,
it will utilize two QMP UNI PHYs for the SSUSB path, and two M31 eUSB2
PHYs for the HSUSB path.

Changes in v6:
- Reworked the reference clock requirements for the QMP and M31 eUSB2
  PHYs.  In the QMP case (both UNI and combo), removed the need for
  the clkref entry, as TCSRCC clkref switches will handle votes on the
  CXO clock.  For entries w/o a TCSRCC clkref switch, populate the ref
  entry to the CXO handle, while others (with TCSRCC entries) will
  the TCSRCC clkref associated to the USB core.
- With the reference clock rework, dropped:
    phy: qualcomm: m31-eusb2: Make clkref an optional resource
- Removed the need for a clkref entry in the QMP combo clocks list.
  Removed previous reviewed-by tag due to this change.
- Split non PHY subsystem based patches into a separate submission.
- Remove DP related init tables from QMP combo
- Link to v5: https://lore.kernel.org/r/20251006222002.2182777-1-wesley.cheng@oss.qualcomm.com

Changes in v5:
- Moved phy-qcom-qmp-usb43-pcs-v8.h into USB specific QMP driver
- Fixed DT bindings for clock properties for QMP combo PHY
- Link to v4: https://lore.kernel.org/r/20251001220534.3166401-1-wesley.cheng@oss.qualcomm.com

Changes in v4:
- Updated DT bindings change for QMP combo PHY to have IF/THEN blocks
to handle the newly added clkref, and fixed the commit message as well
- Added a new header with v8 offsets for the PCS MISC register set,
and refgen current load for the QMP combo PHY driver
- RE-added the headers for the QMP combo PHY
- Link to v3: https://lore.kernel.org/r/20250925022850.4133013-1-wesley.cheng@oss.qualcomm.com

Changes in v3:
- Fixed some incorrect patch ordering.
- Alphabetized Glymur QMP settings for combo and UNI setting arrays
- Link to v2: https://lore.kernel.org/r/20250925005228.4035927-1-wesley.cheng@oss.qualcomm.com

Changes in v2:
- Updated QMP combo PHY to properly handle the refgen-supply and to
remove the primary core reference/tag
- Updated QMP UNI PHY to properly handle the refgen-supply and added
a separate IF/THEN block to handle the new clkref
- Updated M31 eUSB2 to make clocks and clocks-name required for sm8750
and optional for Glymur
- Fixed missing PCS MISC table
- Added SMB2370 repeater changes
- Link to v1: https://lore.kernel.org/r/20250920032108.242643-1-wesley.cheng@oss.qualcomm.com
