The Snapdragon 670 adds and removes some clocks, adds new frequencies, and
adds a new GPLL (Global Phase-Locked Loop) in reference to SDM845, while
also removing some GDSCs. Despite these differences, there are many
similarities with SDM670. Add data for SDM670 in the driver for SDM845 to
reuse the most of the clock data.
Advantages and disadvantages of this approach:
+ maintenance applies to both sdm670 and sdm845 by default
+ less duplicate code (clocks) means smaller distro/pre-built kernels
with all drivers enabled
- clocks for both SoC's must be compiled if the user wants clocks for one
specific SoC (both or none)
- additional testing needed for sdm845 devices

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.
