Devicetree for the FIMC IS camera included duplicated PMU node as its
child like:
soc@0 {
system-controller@10020000 { ... }; // Real PMU
camera@11800000 {
fimc-is@12000000 {
// FIMC IS camera node
pmu@10020000 {
reg = <0x10020000 0x3000>; // Fake PMU node
};
};
};
};
This is not a correct representation of the hardware. Mapping the PMU
(Power Management Unit) IO memory should be via syscon-like phandle
(samsung,pmu-syscon, already used for other drivers), not by duplicating
"pmu" Devicetree node inside the FIMC IS. Backward compatibility is
preserved.

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.
