The rcar DU driver on r8a779a0 has a bug causing some specific colors getting converted to transparent colors, which then (usually) show as black pixels on the screen. The reason seems to be that the driver sets PnMR_SPIM_ALP bit in PnMR.SPIM field, which is an illegal setting on r8a779a0. The PnMR_SPIM_EOR bit also illegal. Add a new feature flag for this (lack of a) feature and make sure the bits are zero on r8a779a0.

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.
