The Adaptive Supply Voltage (ASV) driver adjusts CPU cluster operating points depending on exact revision of an SoC retrieved from the CHIPID block or the OTP memory. This allows for some power saving as for some CPU clock frequencies we can lower CPU cluster's supply voltage comparing to safe values common to all the SoC revisions. This patch adds support for Exynos5422/5800 SoC, it is partially based on code from https://github.com/hardkernel/linux repository, branch odroidxu4-4.14.y, files: arch/arm/mach-exynos/exynos5422-asv.[ch]. Tested on Odroid XU3, XU4, XU3 Lite. Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
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.
