The devicetree bindings for anybus-controller were mistakenly
merged into the main Linux tree. Its driver resides in
staging/, so the bindings belong in staging/ too.

The Anybus-S/Anybus-M is a series of interchangeable fieldbus communication
modules featuring on board memory and processing power. All software and
hardware functionality required to communicate on the fieldbus is
incorporated in the module itself, allowing the application to focus on
other tasks.
Add a driver for the Arcx anybus bridge.
This chip embeds up to two Anybus-S application connectors
(slots), and connects to the SoC via a parallel memory bus.
There is also a CAN power readout, unrelated to the Anybus,
