Alexey Charkov 6cd594ed96 ARM: dts: vt8500: Add L2 cache controller on WM8850/WM8950
WonderMedia WM8850/WM8950 uses an ARM PL310 cache controller for its
L2 cache, add it.

The parameters have been deduced from vendor's U-boot environment
variables, which the downstream code uses to initialize the
controller. They set the following register values:

aux = 0x3e440000
prefetch_ctrl = 0x70000007

Their initialization code also unconditionally sets the flags
L2X0_DYNAMIC_CLK_GATING_EN | L2X0_STNDBY_MODE_EN, so encode those too

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 reStructuredText 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.
