Christian Lamparter a653f2f538 net: dsa: qca8k: introduce reset via gpio feature
The QCA8337(N) has a RESETn signal on Pin B42 that
triggers a chip reset if the line is pulled low.
The datasheet says that: "The active low duration
must be greater than 10 ms".

This can hopefully fix some of the issues related
to pin strapping in OpenWrt for the EA8500 which
suffers from detection issues after a SoC reset.

Please note that the qca8k_probe() function does
currently require to read the chip's revision
register for identification purposes.

README

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.
