Newly introduced mode_set callback in engine structure is a much better place for setting mixer output size and interlace mode for the following reasons: 1. Aforementioned properties change only when mode changes, so it's enough to be set only once per mode set. Currently it's done whenever properties of primary plane are changed. 2. It's assumed that primary plane will always cover whole screen. While this is true most of the time, it's not always. DE2/3 planes are universal and mostly equal in functionality. There is no reason to add artificial limitation to primary planes. 3. The current code only works for UI layers, but some mixers do not have any UI layers.

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.
