Marek Szyprowski ccb69e228e PM / devfreq: exynos: add Exynos PPMU as a soft module dependency
Commit adf8238ef4 ("ARM: dts: exynos: move exynos-bus nodes out of soc
in Exynos4412") changed the order of the exynos-bus nodes, what results
in different probe order of the Exynos Bus devices. Although the driver
properly handles the deferred probe and all devices seems to be finally
properly registered, this change revealed some kind of a bug related to
PPMU counters registration and passive governor operation. Usually in 1
of 10 boots this results in complete board freeze during loading of the
kernel modules.

To avoid that freeze, ensure that the Exynos PPMU driver is already
loaded before the Exynos Bus driver starts probing.

README

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.
