It's not possible to reboot or poweroff Exynos7420 using PSCI. Instead we need to use syscon reboot/poweroff drivers, like it's done for other Exynos SoCs. This was confirmed by checking vendor source and testing it on Samsung Galaxy S6 device based on this SoC. To be able to use custom restart/poweroff handlers instead of PSCI functions, we need to correct psci compatible. This also requires us to provide function ids for CPU_ON and CPU_OFF.

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.
