There are SPI IPs that can be configured by the integrator with a specific FIFO depth depending on the system's capabilities. For example, the samsung USI SPI IP can be configured by the integrator with a TX/RX FIFO from 8 byte to 256 bytes. Introduce the ``fifo-depth`` property for such instances of IPs where the same FIFO depth is used for both RX and TX. Introduce ``rx-fifo-depth`` and ``tx-fifo-depth`` properties for cases where the RX FIFO depth is different from the TX FIFO depth. Make the dedicated RX/TX properties dependent on each other and mutual exclusive with the other.

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.
