From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lennert Buytenhek Subject: [PATCH] smc91x: disable DMA mode on the logicpd pxa270 Date: Fri, 23 Jun 2006 23:24:36 +0200 Message-ID: <20060623212436.GB4843@xi.wantstofly.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: nico@cam.org, mikee@logicpd.com, peterb@logicpd.com Return-path: Received: from alephnull.demon.nl ([83.160.184.112]:55472 "EHLO xi.wantstofly.org") by vger.kernel.org with ESMTP id S1752079AbWFWVYh (ORCPT ); Fri, 23 Jun 2006 17:24:37 -0400 To: jgarzik@pobox.com, netdev@vger.kernel.org Content-Disposition: inline Sender: netdev-owner@vger.kernel.org List-Id: netdev.vger.kernel.org Enabling PXA DMA for the smc91x on the logicpd pxa270 produces unacceptable interference with the TFT panel, so disable it. Also delete the lpd270 versions of the SMC_{in,out}[bl]() macros, as they aren't used, since the board only supports 16bit accesses.
