Subject: [PATCH v2 2/7] DT: phy.txt: Add mdio-integrated-mux property
Date: Tue, 31 May 2016 19:06:36 +0530 [thread overview]
Message-ID: <1464701801-17243-3-git-send-email-pramod.kumar@broadcom.com> (raw)
In-Reply-To: <1464701801-17243-1-git-send-email-pramod.kumar@broadcom.com>
This property is used by integrated MDIO multiplexer
which has bus selection and mdio transaction generation logic,
integrated inside.
