Maarten Lankhorst 2ac45bdd92 drm/i915/psr: Add debugfs support to force a downgrade to PSR1 mode.
This will make it easier to test PSR1 on PSR2 capable eDP machines.

Changes since v1:
- Remove I915_PSR_DEBUG_FORCE_PSR2, it did nothing, not sure forcing
  PSR2 would even work.
- Handle NULL crtc in intel_psr_set_debugfs_mode. (dhnkrn)

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.
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.
