From: Fabio Baltieri Date: Wed, 12 Jun 2013 07:57:58 +0000 (+0200) Subject: ASoC: ux500: Set DMA address during device init X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=20413113ffdd8c56b2a985ca8195d9c91e9c602b;p=deliverable%2Flinux.git ASoC: ux500: Set DMA address during device init Add a field with the tx/rx register address to the DMA parameters structure, and set it to the correct address during device initialization. This address used to be hardcoded in the DMA controller driver, it now needs to be explicitly figured out by the device driver.
