Exynos 9810 is an ARMv8 mobile SoC found in various Samsung devices, such as Samsung Galaxy S9 (starlte), S9 Plus (star2lte), Note 9 (crownlte) and perhaps others. Add minimal support for this SoC, including basic stuff like: - PSCI for bringing up secondary cores - ARMv8 generic timer - GPIO and pinctrl. The firmware coming with the devices based on this SoC is buggy and doesn't configure CNTFRQ_EL0, as required by spec, so it's needed to hardcode the frequency in the timer node.

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.
