Subject: [PATCH 2/2] dt-bindings: net: dwmac: document 'mac-mode' property
Date: Fri, 6 Sep 2019 16:02:56 +0300	[thread overview]
Message-ID: <20190906130256.10321-2-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20190906130256.10321-1-alexandru.ardelean@analog.com>

This change documents the 'mac-mode' property that was introduced in the
'stmmac' driver to support passive mode converters that can sit in-between
the MAC & PHY.
