[ Upstream commit 59cb403f38099506ddbe05fd09126f3f0890860b ]
DCSS supports 90/180/270 degree rotations for Vivante tiled and super-tiled
formats. Unfortunately, with the current code, they didn't work properly.
This simple patch makes the rotations work by fixing the way the scaler is set
up for 90/270 degree rotations. In this particular case, the source width and
height need to be swapped since DPR is sending the buffer to scaler already
rotated.
Also, make sure to allow full rotations for DRM_FORMAT_MOD_VIVANTE_SUPER_TILED.

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.
