Subject: [PATCH v2 00/13] Add DisplayPort support for QCS615 platform

This series aims to extend the USB-C PHY to support DP mode and enable
DisplayPort on the Qualcomm QCS615 platform.

The devicetree modification for DisplayPort on QCS615 will be provided
in a future patch.

- Update DP PHY configuration flow to align with QMP Combo PHY implementation [Dmitry]
- Update all hex values to lowercase [Dmitry]
- Remove redundant comments in DP PHY driver [Krzysztof]
- Remove invalid USBC type define [Dmitry]
- Move lane_map， max_dp_lanes， max_dp_link_rate parsing logic to dp_link [Dmitry]
- Add TCSR-based mutex logic for DP and USB PHY coexistence [Dmitry]
- Drop patches 6–8 and remove related binding properties as rejected upstream
