mainlining shenanigans
b36a6bb8a1
Currently only linear formats are supported in sun4i-drm driver, but SoCs like H6 supports AFBC variant of some of them in multiple cores (GPU, VPU, DE3). Panfrost already implements AFBC compression and is sometimes confused what should be default choice (linear, AFBC) if DRM driver is not explicit about modifier support (MiniMyth2 distro with MythTV app). After some discussion with Daniel Stone on #panfrost IRC, it was decided to make modifiers in sun4i-drm explicit, to avoid any kind of guessing, not just in panfrost, but everywhere. In fact, long term idea is to make modifier parameter in drm_universal_plane_init() mandatory (non NULL).

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.
