Currently ALPM parameters are computed directly into
intel_dp->alpm_parameters. This is a problem when compute config ends up to
not using the computed state.
Fix this by adding ALPM parameters into intel_crtc_state and compute into
there. Copy needed parameters (io_wake_lines and fast_wake_lines used by
PSR activate/exit) from crtc_state->alpm_state into
intel_dp->alpm.alpm_parameters when they are configured into HW.
v3:
- enhance commit message
v2:
- store io/fast wake lines into intel_dp->dp instead of
intel_dp->alpm_parameters and do it in intel_psr_enable_locked
- rename crtc_state->alpm_parameters -> crtc_state->alpm_state
- clarify commit message

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.
