Recheck the link state after a passing link training, with a 2 sec delay to account for cases where the link goes bad following the link training and the sink doesn't report this via an HPD IRQ. The delayed work added here will be also used by a later patch after a failed link training to try to retrain the link with unchanged link params before reducing the link params. v2: Don't flush an uninitialized delayed work (on HDMI-only DDI ports). v3: - Move the helpers to a new intel_encoder.c file, rename them accordingly. (Ville) - Add the work to intel_encoder instead of intel_digital_port. - Call the encoder specific link check function via an encoder hook. - Flush the link check work during encoder destroy from intel_dp_encoder_flush_work(). - Flush the link check work during encoder suspend as well. v4: Call intel_encoder_link_check_init() with a valid encoder pointer.

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.
