The i2c bus on imx6qdl-wandboard has intermittent issues where SDA can freeze on low level at the end of transaction so the bus can no longer work. This impacts reading of EDID data leading to incorrect TV resolution and no audio. This scenario is improved by adding scl/sda gpios definitions to implement the i2c bus recovery mechanism.

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.
