==================== net: Add Half Duplex support for ICSSG Driver This series adds support for half duplex operation for ICSSG driver. In order to support half-duplex operation at 10M and 100M link speeds, the PHY collision detection signal (COL) should be routed to ICSSG GPIO pin (PRGx_PRU0/1_GPI10) so that firmware can detect collision signal and apply the CSMA/CD algorithm applicable for half duplex operation. A DT property, "ti,half-duplex-capable" is introduced for this purpose in the first patch of the series. If board has PHY COL pin conencted to PRGx_PRU1_GPIO10, this DT property can be added to eth node of ICSSG, MII port to support half duplex operation at that port. Second patch of the series configures driver to support half-duplex operation if the DT property "ti,half-duplex-capable" is enabled. This series addresses comments on [v2]. This series is based on the latest net-next/main. This series has no dependency. Changes from v1 to v2: *) Changed the description of "ti,half-duplex-capable" property as asked by Rob and Andrew to avoid confusion between capable and enable. Changes from v1 to v2: *) Dropped the RFC tag. *) Added RB tags of Andrew and Roger.

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.
