Imre Deak 39818c06c8 drm/i915/dp: Add DP tunnel atomic state and check BW limit
Add the atomic state during a modeset required to enable the DP tunnel
BW allocation mode on links where such a tunnel was detected. This state
applies to an already enabled output, the state added for a newly
enabled output will be computed and added/cleared to/from the atomic
state in a follow-up patch.

v2:
- s/old_crtc_state/crtc_state in intel_crtc_duplicate_state().
- Move intel_dp_tunnel_atomic_cleanup_inherited_state() to a follow-up
  patch adding the corresponding state. (Ville)
- Move intel_dp_tunnel_atomic_clear_stream_bw() to a follow-up
  patch adding the corresponding state.

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.
