Add the KMS plane rotation property to the DRM rockchip driver,
for SoCs RK3328, RK3368 and RK3399.
RK3288 only supports rotation at the display level (i.e. CRTC),
but for now we are only interested in plane rotation.
This commit only adds support for the value of reflect-y
and reflect-x (i.e. mirroring).
Note that y-mirroring is not compatible with YUV.
The following modetest commands would test this feature,
where 30 is the plane ID, and 49 = rotate_0 + relect_y + reflect_x.
X mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:17
Y mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:33
XY mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:49

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.
