As per DP spec the timeout for LANE_CHANNEL_EQ_DONE is 400ms. But this timeout value is exclusively for the Aux RD Interval and excludes the time consumed for the AUX Tx (i.e reading/writing FFE presets). Add another 50ms for these AUX Tx to the 400ms timeout. Ref: "Figure 3-52: 128b132b DP DPTC LANEx_CHANNEL_EQ_DONE Sequence" of DP2.1a spec.

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.
