From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andy Fleming Subject: [PATCH 2/4] gianfar: Add phy-connection-type to gianfar nodes Date: Mon, 16 Jul 2007 20:26:59 -0500 Message-ID: <11846356233423-git-send-email-afleming@freescale.com> References: <1184635621688-git-send-email-afleming@freescale.com> <1184635622653-git-send-email-afleming@freescale.com> Cc: netdev@vger.kernel.org, linuxppc-dev@ozlabs.org, Andy Fleming To: jgarzik@pobox.com, paulus@samba.org, galak@kernel.crashing.org Return-path: Received: from de01egw02.freescale.net ([192.88.165.103]:35662 "EHLO de01egw02.freescale.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1755929AbXGQB1g (ORCPT ); Mon, 16 Jul 2007 21:27:36 -0400 In-Reply-To: <1184635622653-git-send-email-afleming@freescale.com> Sender: netdev-owner@vger.kernel.org List-Id: netdev.vger.kernel.org The TSEC/eTSEC automatically detect their PHY interface type, unless the type is RGMII-ID (RGMII with internal delay). In that situation, it just detects RGMII. In order to fix this, we need to pass in rgmii-id if that is the connection type.
