The Analogix 7737 DP to HDMI converter requires reduced M and N values when to operate correctly at HBR2. We tried to reduce the M/N values for all devices in commit9a86cda07a("drm/i915/dp: reduce link M/N parameters"), but that regressed some other sinks. Detect this IC by its OUI value of 0x0022B9 via the DPCD quirk list, and only reduce the M/N values for that. v2 by Jani: Rebased on the DP quirk database v3 by Jani: Rebased on the reworked DP quirk database v4 by Jani: Improve commit message (Daniel) Fixes:9a86cda07a("drm/i915/dp: reduce link M/N parameters") Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=93578 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=100755 Cc: Jani Nikula <jani.nikula@intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Clint Taylor <clinton.a.taylor@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/2d2e30f8f47d3f28c9b74ca2612336a54585c3ec.1495105635.git.jani.nikula@intel.com
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
