With commit222ec1618c("drm: Add aspect ratio parsing in DRM layer") the drm core started honoring the picture_aspect_ratio field when comparing two drm_display_modes. Prior to that it was ignored. When the CVBS encoder driver was initially submitted there was no aspect ratio check. Switch from drm_mode_equal() to drm_mode_match() without DRM_MODE_MATCH_ASPECT_RATIO to fix "kmscube" and X.org output using the CVBS connector. When (for example) kmscube sets the output mode when using the CVBS connector it passes HDMI_PICTURE_ASPECT_NONE, making the drm_mode_equal() fail as it include the aspect ratio. Prior to this patch kmscube reported: failed to set mode: Invalid argument The CVBS mode checking in the sun4i (drivers/gpu/drm/sun4i/sun4i_tv.c sun4i_tv_mode_to_drm_mode) and ZTE (drivers/gpu/drm/zte/zx_tvenc.c tvenc_mode_{pal,ntsc}) drivers don't set the "picture_aspect_ratio" at all. The Meson VPU driver does not rely on the aspect ratio for the CVBS output so we can safely decouple it from the hdmi_picture_aspect setting.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
