Ankit Nautiyal 0ec46988ae drm/i915/vrr: Allow fixed_rr with pipe joiner
VRR with joiner is currently disabled as it still needs some work to
correctly sequence the primary and secondary transcoders. However, we can
still use VRR Timing generator in fixed refresh rate for joiner and since
it just need to program vrr timings once and does not involve changing
timings on the fly. We still need to skip the VRR and LRR for joiner.

To achieve this set vrr.in_range to 0 for joiner case, so that we do not
try VRR and LRR for the joiner case.

v2: Avoid checks for secondary pipes, where not required. (Ville)
v3: Remove a redundant check and reset vrr.in_range to false. (Ville)

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.
