From e902b2b063a67517922bf4e154258ed27db34b8b Mon Sep 17 00:00:00 2001
From: Biju Das <biju.das@bp.renesas.com>
Date: Thu, 2 Apr 2015 13:16:44 +0100
Subject: [PATCH 5/7] ARM: shmobile: porter: Sound DMA support via SRC on DTS
DMA transfer to/from SRC
DMA DMApp
[MEM] -> [SRC] -> [SSIU] -> [SSI]
DMA DMApp
[MEM] <- [SRC] <- [SSIU] <- [SSI]
Current sound driver is supporting
SSI/SRC random connection.
So, this patch is tring
SSI0 -> SRC0
SSI1 <- SRC1
This change is identical to the koelsch patch "ARM: shmobile: koelsch: Sound DMA support via SRC on DTS"
from Kuninori Morimoto and backported to 3.10
