Subject: [PATCH v2] dt-bindings: net: renesas,etheravb: Document Gigabit Ethernet IP
Date: Tue, 27 Jul 2021 13:34:50 +0100 [thread overview]
Message-ID: <20210727123450.15918-1-biju.das.jz@bp.renesas.com> (raw)
Document Gigabit Ethernet IP found on RZ/G2L SoC.

Internal TCP/IP Offload Engine (TOE) and Dedicated Direct memory
access controller (DMAC) for transferring transmitted Ethernet
frames to and received Ethernet frames from respective storage
areas in the URAM at high speed.
