From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jarkko Nikula Subject: [PATCH 2/2] ASoC: Intel: Use ACPI device for Baytrail PCM buffer allocation Date: Fri, 9 May 2014 16:47:44 +0300 Message-ID: <1399643264-7669-2-git-send-email-jarkko.nikula@linux.intel.com> References: <1399643264-7669-1-git-send-email-jarkko.nikula@linux.intel.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Received: from mga02.intel.com (mga02.intel.com [134.134.136.20]) by alsa0.perex.cz (Postfix) with ESMTP id 05344261A5A for ; Fri, 9 May 2014 15:48:21 +0200 (CEST) In-Reply-To: <1399643264-7669-1-git-send-email-jarkko.nikula@linux.intel.com> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: alsa-devel-bounces@alsa-project.org Sender: alsa-devel-bounces@alsa-project.org To: alsa-devel@alsa-project.org Cc: Liam Girdwood , Mark Brown , Jarkko Nikula , Liam Girdwood List-Id: alsa-devel@alsa-project.org This follows the same idea than commit 10df350977b1 ("ASoC: Intel: Fix Audio DSP usage when IOMMU is enabled.") by using only ACPI device for all DMA allocations. Since DMA masking is already done in firmware loading it can be removed from here.
