Document the USB2 PHY controller for the Renesas RZ/T2H (r9a09g077) and RZ/N2H (r9a09g087) SoCs. These SoCs share the same PHY block, which is similar to the one on RZ/G2L but differs in clocks, resets, and register bits. To account for these differences, a new compatible string `renesas,usb2-phy-r9a09g077` is introduced. The RZ/N2H SoC uses the same PHY as RZ/T2H, so it reuses the RZ/T2H compatible string as a fallback.

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.
