Linux kernel source tree
be5f81d37f
Instead of using hard coded clock increment values for each SoC derive the clock increment from the module clock. This is done in preparation to support a second platform, R-Car V4H that uses a 200Mhz clock compared with the 320Mhz clock used on R-Car S4. Tested on both SoCs, S4 reports a clock of 320000000Hz which gives a value of 0x19000000. Documentation says a 320Mhz clock is used and the correct increment for that clock is 0x19000000. V4H reports a clock of 199999992Hz which gives a value of 0x2800001a. Documentation says a 200Mhz clock is used and the correct increment for that clock is 0x28000000.

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.
