From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jason Gunthorpe Subject: [PATCH v2 1/2] dt: Document a compatible entry for MDIO ethernet Phys Date: Fri, 31 Jan 2014 14:50:44 -0700 Message-ID: <1391205045-1751-1-git-send-email-jgunthorpe@obsidianresearch.com> Cc: Grant Likely , linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, netdev-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Rob Herring Return-path: Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: netdev.vger.kernel.org This describes a compatible entry of the form: ethernet-phy-idAAAA,BBBB Which is modelled after the PCI structured compatible entry (pciVVVV,DDDD.SSSS.ssss.RR) If present the OF core will be able to use this information to directly create the correct phy without auto probing the bus.
