Maxime Ripard 6d7b41a676 drm/sun4i: frontend: Rework a bit the phase data
[ Upstream commit 84c971b356379c621df595bd00c3114579dfa59f ]

The scaler filter phase setup in the allwinner kernel has two different
cases for setting up the scaler filter, the first one using different phase
parameters for the two channels, and the second one reusing the first
channel parameters on the second channel.

The allwinner kernel has a third option where the horizontal phase of the
second channel will be set to a different value than the vertical one (and
seems like it's the same value than one used on the first channel).
However, that code path seems to never be taken, so we can ignore it for
now, and it's essentially what we're doing so far as well.

Since we will have always the same values across each components of the
filter setup for a given channel, we can simplify a bit our frontend
structure by only storing the phase value we want to apply to a given
channel.

README

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.
