From mboxrd@z Thu Jan 1 00:00:00 1970 From: David Daney Subject: [PATCH 2/3] netdev/phy/of: Handle IEEE802.3 clause 45 Ethernet PHYs in of_mdiobus_register() Date: Wed, 12 Oct 2011 11:06:22 -0700 Message-ID: <1318442783-29058-3-git-send-email-david.daney@cavium.com> References: <1318442783-29058-1-git-send-email-david.daney@cavium.com> Cc: afleming@gmail.com, David Daney To: devicetree-discuss@lists.ozlabs.org, grant.likely@secretlab.ca, linux-kernel@vger.kernel.org, netdev@vger.kernel.org, davem@davemloft.net Return-path: In-Reply-To: <1318442783-29058-1-git-send-email-david.daney@cavium.com> Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org Define two new "compatible" values for Ethernet PHYs. "ethernet-phy-ieee802.3-c22" and "ethernet-phy-ieee802.3-c45" are used to indicate a PHY uses the corresponding protocol. If a PHY is "compatible" with "ethernet-phy-ieee802.3-c45", we indicate this so that get_phy_device() can properly probe the device.
