commit20c2dbff34upstream. Apparently some BXT/GLK systems have DSI panels whose timings don't agree with the normal cpu transcoder hblank>=32 limitation. This is perhaps fine as there are no specific hblank/etc. limits listed for the BXT/GLK DSI transcoders. Move those checks out from the global intel_mode_valid() into into connector specific .mode_valid() hooks, skipping BXT/GLK DSI connectors. We'll leave the basic [hv]display/[hv]total checks in intel_mode_valid() as those seem like sensible upper limits regardless of the transcoder used.

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.
