From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tony Lindgren Subject: [PATCH 06/12] ARM: dts: Add support for Ethernet on some N900 macro boards Date: Mon, 15 Sep 2014 20:12:00 -0700 Message-ID: <1410837126-31553-6-git-send-email-tony@atomide.com> References: <1410837126-31553-1-git-send-email-tony@atomide.com> Return-path: Received: from mho-03-ewr.mailhop.org ([204.13.248.66]:19976 "EHLO mho-01-ewr.mailhop.org" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S1754369AbaIPDNJ (ORCPT ); Mon, 15 Sep 2014 23:13:09 -0400 In-Reply-To: <1410837126-31553-1-git-send-email-tony@atomide.com> Sender: linux-omap-owner@vger.kernel.org List-Id: linux-omap@vger.kernel.org To: linux-omap@vger.kernel.org Cc: linux-arm-kernel@lists.infradead.org As we have support for this in board-rx51-peripherals.c, let's add it to the .dts files too. Note that the reset GPIO will eventually go to the driver. For now let's just pull it down and skip any further reset in case the bootloader has configured the MAC address so NFSroot works. Also note that after 3430-sdp are using proper GPMC timings we can remove the tests for smsc,lan91c94 in gpmc.c.
