[PATCH v2 05/28] dt-bindings: net: Add support for QMC HDLC

From: Herve Codina <herve.codina@bootlin.com>
Date: 2023-07-26 15:03:30
Also in: alsa-devel, linux-devicetree, linux-gpio, linuxppc-dev, lkml
Subsystem: networking drivers, open firmware and flattened device tree bindings, the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

The QMC (QUICC mutichannel controller) is a controller present in some
PowerQUICC SoC such as MPC885.
The QMC HDLC uses the QMC controller to transfer HDLC data.
