Andy Yan c83df779fd drm/rockchip: vop2: Add uv_mst and ymirror register for Esmart/Smart win
Smart and Esmart support yuv and ymirror, But all the multi area in
one windows share the same ymirror bits. This give a strict limitation
on compositor: the compositor must enable DRM_MODE_REFLECT_Y for all
the multi area plane or disable all of them, otherwise will cause
a iommu pagefault as multie area don't know how to fetch data
from framebuffer.

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.
