From 832290b25e20e0c3a6da056f7d0999de51311f2c Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 25 Jun 2012 03:39:20 -0700 Subject: ARM: shmobile: sh73a0: add DMAEngine support for MPDMAC Current shdmac can support MPDMAC (= sound DMA) on sh73a0. This support reduce CPU load when sound was playback. On v2.0 manual, MPDMAC MID/RID number were wrong. This patch is using the number which seems correct.
