MLK-13862-1 epdc/pxp: imx7d: enhance the LUT cleanup flow to avoid stalling display
Robby Cai authored
- change from wfe_b to wfe_a, and modifiy register settings to support new flow
- the underlying design policy change as follows.
  in previous flow, when all LUTs are used, the LUT cleanup operation
  need to wait for all the LUT to finish, it will not happen util last LUT
  is done. while in new flow, the cleanup operation does not need to wait
  for all LUTs to finish, instead it can start when there's LUT's done.
  The saved time is multiple LUT operation time.

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.
