Document support for the Serial Communication Interface with FIFO (SCIF) available in the Renesas RZ/V2H(P) (R9A09G057) SoC. The SCIF interface in the Renesas RZ/V2H(P) is similar to that available in the RZ/G2L (R9A07G044) SoC, with the following differences: - RZ/V2H(P) SoC has three additional interrupts: one for Tx end/Rx ready and two for Rx and Tx buffer full, all of which are edge-triggered. - RZ/V2H(P) supports asynchronous mode, whereas RZ/G2L supports both synchronous and asynchronous modes. - There are differences in the configuration of certain registers such as SCSMR, SCFCR, and SCSPTR between the two SoCs. To handle these differences in the driver, a new SoC-specific compatible string is added, ensuring proper handling of the unique features and register configurations of the RZ/V2H(P) SoC.

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.
