The imx6sl chip errata document describes ERR006287 like this: > Upon resuming from power gating, the modules in the display power domain (eLCDIF, EPDC, PXP and SPDC) might fail to perform register reads correctly. > When the modules listed above are used, do not use power gating on the display power domain. Link: https://www.nxp.com/docs/en/errata/IMX6SLCE.pdf#page=62 Handle this in the safest possible way by keeping the DISP domain always-on.

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.
