This will find the connector mode combo that fits into the bandwidth when more than one monitor is connected. Example: When two monitors connected through MST, the second monitor also tries to use the same mode. So two such modes may not fit into the link bandwidth. So, iterate through connected outputs & modes and find a combination of modes those fit into the link BW. v2: -Updated commit msg and description. (Bhanu) -Renamed restart with retry. (Bhanu) -Moved igt_pipe_crc_new before retry. (Bhanu) -Removed unrelated changes and new line. (Bhanu) -Minor changes. v3: Updated discription and added EINVAL check. v4: Removed EINVAL and ENOSPC checks. Added check for DP-MST and 4k panels. Updated discription. v5: Defined 4k display modes globally. v6: -Removed if loop checks. -Added igt override to avoid dp mst bw failure. v7: Resolved conflict. v8: Removed igt_display_reset from called function.
