From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lee Jones Subject: [PATCH 05/11] ASoC: ux500_pcm: Stop pretending that we support varying address widths Date: Thu, 19 Dec 2013 15:55:02 +0000 Message-ID: <1387468508-12286-6-git-send-email-lee.jones@linaro.org> References: <1387468508-12286-1-git-send-email-lee.jones@linaro.org> Return-path: In-Reply-To: <1387468508-12286-1-git-send-email-lee.jones@linaro.org> Sender: linux-kernel-owner@vger.kernel.org To: linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org Cc: linus.walleij@linaro.org, broonie@kernel.org, alsa-devel@alsa-project.org, Lee Jones List-Id: alsa-devel@alsa-project.org The Slave Config's addr_width attribute is populated by data_width of dma_cfg, which in turn is derived from dma_params' data_size attribute and that comes from the slot_width which is always 16 bits (2 Bytes). We're cutting out the middle man here and just setting the DMA Slave Config directly.
