Subject: [PATCH 05/11] ASoC: ux500_pcm: Stop pretending that we support varying address widths
Date: Thu, 19 Dec 2013 15:55:02 +0000 [thread overview]
Message-ID: <1387468508-12286-6-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1387468508-12286-1-git-send-email-lee.jones@linaro.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.
