Subject: [RFC 12/13] dt-bindings: net: Add ICSSG Ethernet Driver bindings
Date: Wed, 6 Apr 2022 15:13:57 +0530 [thread overview]
Message-ID: <20220406094358.7895-13-p-mohan@ti.com> (raw)
In-Reply-To: <20220406094358.7895-1-p-mohan@ti.com>
Add a YAML binding document for the ICSSG Programmable real time unit
based Ethernet driver. This driver uses the PRU and PRUSS consumer APIs
to interface the PRUs and load/run the firmware for supporting ethernet
functionality.
