[PATCH v3 0/4] phy: qualcomm: qmp-combo: update DP PHY PLL programming on Glymur

[Nabige Aala]

The existing DP PHY PLL and AUX configuration for the Glymur platform
does not fully follow the Hardware Programming Guide requirements for
DP over Type-C, which results in DP link bring-up failures.

Update the DP PHY programming sequence and PLL-related register
settings to align with the latest HPG recommendations. With this
change, DP link training completes successfully on Glymur-based
platforms.

settings for Glymur platforms")

Changes in v2:
- Use the DP-specific v8 COM status register definitions
(DP_QSERDES_V8_COM_C_READY_STATUS and DP_QSERDES_V8_COM_CMN_STATUS)
instead of adding new N3 USB/DP variants.(Konrad)
- Drop the qmp_v8_combo_configure_dp_mode() implementation and
reuse the common qmp_combo_configure_dp_mode() helper, restoring
orientation-specific DP_PHY_MODE programming (0x4c/0x5c) and addressing
review comments regarding DP_PHY_MODE handling.
- Include phy-qcom-qmp-dp-qserdes-com-v8.h for the DP COM register
definitions.
- Update patch author to Ritesh Kumar.(Konrad)

Changes in v3:
- Split the monolithic patch into a logical 4-patch series (Dmitry):
  - Patch 1: Add DP COM v8 header and fix register layout
  - Patch 2: Update DP PHY common init tables
  - Patch 3: Update link rate specific DP PHY tables
  - Patch 4: Rework DP PHY runtime configuration
- Improved commit messages with detailed explanations for each change
- Better separation of concerns: header additions, table updates, and
runtime logic changes are now in separate patches for easier review
