Document the bindings for STM32 COMBOPHY interface, used to support the PCIe and USB3 stm32mp25 drivers. Following entries can be used to tune caracterisation parameters - st,output-micro-ohms and st,output-vswing-microvolt bindings entries to tune the impedance and voltage swing using discrete simulation results - st,rx-equalizer register to set the internal rx equalizer filter value.

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.
