Changes in v5: - Link to v4: https://lore.kernel.org/all/20260812073002.328-1-kernel@airkyi.com/ - Change the upper bound check for target_mbps from < to <= (sashiko). Changes in v4: - Link to v3: https://lore.kernel.org/all/20260810034139.148-1-kernel@airkyi.com/ - 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@airkyi.com/ - Rebase to Linux v7.2 Changes in v2: - Link to v1: https://lore.kernel.org/all/20260324085838.90-1-kernel@airkyi.com/ - Fix the unit conversion for max_mbps. - Split the lane rate calculation into a separate patch. - Add more comment about timing config.
