From: Chaoyi Chen <chaoyi.chen@xxxxxxxxxxxxxx>

This series is dedicated to enhancing the DSI controller and PHY timing
interaction, refining the lane rate calculation, and addressing the
associated hardware limitations.

Changes in v4:
- Link to v3: https://lore.kernel.org/all/20260810034139.148-1-kernel@xxxxxxxxxx/
- Add missing RK3506 timing and the fallback path for get_timing
(sashiko).
- Fix potential overflow and underflow issues in bandwidth
calculation(sashiko).

Changes in v3:
- Link to v2: https://lore.kernel.org/all/20260603033532.164-1-kernel@xxxxxxxxxx/
- Rebase to Linux v7.2

Changes in v2:
- Link to v1: https://lore.kernel.org/all/20260324085838.90-1-kernel@xxxxxxxxxx/
- Fix the unit conversion for max_mbps.
- Split the lane rate calculation into a separate patch.
- Add more comment about timing config.

Chaoyi Chen (3):
drm/rockchip: dsi: Add maximum per lane bit rate calculation
drm/rockchip: dsi: Add dphy_get_timing support for multiple PHY types
drm/rockchip: dsi: Relax the lane rate margin requirements
