[6.6] regression: no composite video output on RPi4 #5814
With kernel 6.6 (currently 6.6.8 from rpi-update next) composite output doesn't work on RPi4. kmsprint shows the connector and encoder, but no crtc or planes and the video output stays black.
Describe the bug
With kernel 6.6 (currently 6.6.8 from rpi-update next) composite output doesn't work on RPi4. kmsprint shows the connector and encoder, but no crtc or planes and the video output stays black.
On kernel 6.1 from RPiOS apt-update composite output is fine.
Steps to reproduce the behaviour
Enable composite via config.txt and cmdline.txt.
config.txt add the composite parameter to the vc4kms-v3d overlay
cmdline.txt add
video=Composite-1:720x576@50ie
to the endDevice (s)
