Stop with the VBT AUX CH sanitation, and instead just check that the appropriate AUX CH is still available when initializing a DP/TC port. The reason being that we want to start initializing ports in VBT order to deal with VBTs that declare child devices with seemingly conflicting ports. As the encoder initialization can fail for other reasons (at least for eDP+AUX) we can't know upfront which way the conflicts should be resolved. Note that the old way of sanitizing gave priority to the last port declared in the VBT, but now we sort of do the opposite by favoring the first encoder to successfully initialize. The reason for the old "last port wins" preference was eg. Asrock B250M-HDV where port A (eDP) and port E (DP->VGA) have an AUX CH conflict and we need to prefer port E. However with the new way port A (eDP) will be probed first, but will fail to probe due to HPD and thus port E will still win in the end. v2: Pimp the commit message (Jani) Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230630155846.29931-5-ville.syrjala@linux.intel.com
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.
