The patches were generated from the RPi repo with the following command: git format-patch v6.6.34..rpi-6.1.y Some patches needed rebasing and, as usual, the applied and reverted, wireless drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0923/1085] drm: Add DRM_MODE_TV_MODE_MONOCHROME
|
|
|
|
Add this as a value for enum_drm_connector_tv_mode, represented
|
|
by the string "Mono", to generate video with standard timings
|
|
but no colour encoding or bursts. Define it to have no pedestal
|
|
(since only NTSC-M calls for a pedestal).
|
|
|
|
Change default mode creation to acommodate the new tv_mode value
|
|
which comprises both 525-line and 625-line formats.
|
