If the R-Car system controller is described in DT, the rcar-sysc driver
configures SYSCIER and SYSCIMR based on the SoC-specific power area
definitions in r8a779*-sysc. The platform code still passed this
information to the rcar-sysc driver, for compatibility with old R-Car H2
and M2-W DTBs predating commit 8574de8619 ("ARM: dts: r8a7791: Add
SYSC PM Domains") in v4.7. The time has come to drop backwards
compatibility, and delegate everything to the DT enabled rcar-sysc
driver.
After the removal of the legacy SMP fallbacks, which powered up the SCUs
explicitly, there is no longer a need to force an early initialization
of the rcar-sysc driver. It will be initialized in time for secondary
CPU bringup by its early_initcall().
Hence all explicit SYSC configuration and initialization can be removed
from the R-Car Gen2 platform code.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
