Subject: [PATCH v3 1/8] dt-bindings: net: add schema for ASIX USB Ethernet controllers
Date:   Tue, 15 Feb 2022 09:09:30 +0100
Message-Id: <20220215080937.2263111-1-o.rempel@pengutronix.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Create schema for ASIX USB Ethernet controllers and import some of
currently supported USB IDs form drivers/net/usb/asix_devices.c

This devices are already used in some of DTs. So, this schema makes it official.
NOTE: there was no previously documented txt based DT binding for this
controllers.
