From f892afb07eeecf575179c4747952644a82a92a36 Mon Sep 17 00:00:00 2001 From: Nicolin Chen Date: Mon, 16 Jun 2014 11:31:05 +0800 Subject: dmaengine: imx-sdma: Add a new DMATYPE for Shared Peripheral ASRC Shared Peripheral ASRC, running on SPBA, needs to use shp sciprts for DMA transfer. So this patch just adds a new DMATYPE for it.

Such a use case is audio, where it is preferred that it is served with highest priority compared to other DMA clients.
