All CortexA7/A15 based Exynos5 SoCs have ARM architected timers, so enable support for them directly in the base dtsi. None of the known firmware properly configures CNTFRQ arch timer register, so force clock frequency to 24MHz, which is the only configuration supported by the remaining clock drivers so far. Stock firmware for Peach Pit and Pi Chromebooks also doesn't reset properly other arch timer registers, so add respective properties indicating that. Other Exynos5-based boards behaves correctly in this area, what finally allows to enable support for KVM-based virtualization.

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.
