Add EDID support to sysfb connector helpers. Read the EDID property from the OF node in ofdrm. Without EDID, this does nothing. Some systems with OF display, such as 32-bit PPC Macintoshs, provide the system display's EDID data as node property in their DT. Exporting this information allows compositors to implement correct DPI and meaningful color management. v3: - avoid parser error by clearing EDID extension field v2: - return errno codes on errors (Jani) - simplify EDID read logic (Jani) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://lore.kernel.org/r/20250401094056.32904-13-tzimmermann@suse.de
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 reStructuredText 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.
