Subject: [PATCH V2 1/3] Documentation: devicetree: add multiple cpu port DSA binding
Date: Tue, 30 May 2017 12:44:17 +0200 [thread overview]
Message-ID: <20170530104419.6052-1-john@phrozen.org> (raw)
Extend the DSA binding documentation, adding the new property required
when there is more than one CPU port attached to the switch.
