Document compatible string for Exynos7870 DWC3-compatible USB 2.0 driver. The devicetree node requires three clocks, named "bus_early", "ref", and "ctrl". Unlike other variants, Exynos7870's USB controller requires a single 3.0V regulator. Assert that the other 1.0V regulator requirement is enforced on variants individually other than Exynos7870's.

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 reStructuredText 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.
