====================
IP101GR: devicetree based configuration of SEL_INTR32
The IP101GR is a 32-pin QFN package variant of the IP101G/IP101GA
Ethernet PHY. Due to it's limited amount of pins the RXER (receive
error) and INTR32 (interrupt) functions share pin 21.
The goal of this series is:
- some small cleanups in patches 3, 4 and 5
- allowing the kernel to detect IRQ floods on boards where the IP101GR
is configured in RXER mode but the RXER line is configured on the
host SoC as interrupt line (patch 6)
- configuration of the SEL_INTR32 register so we can use the interrupt
function on boards where the RXER/INTR32 pin (pin 21) is routed to
one of the host SoC's interrupt inputs (patches 1, 2, 7)
A use-case where this is needed is the Endless Mini (EC-100). I have
tested my changes on that board. This also confirms that Heiner
Kallweit's recent icplus.c PHY driver changes are working (at least on
my setup).
This series is based on net-next commit

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.
