[PATCH 0/1] ARM: configs: remove all CONFIG_RCAR_AUDMAC_PP from ARM defconfigs

[Kuninori Morimoto]

Hi Olof, Kevin, Arnd

This patch removes CONFIG_RCAR_AUDMAC_PP from arch/arm/configs,
because rcar_audmac_periperi is no longer DMAEngine driver.

DMAEngine maintainer Vinod accepted about rcar_audmac_periperi removal patch on

	git://git.infradead.org/users/vkoul/slave-dma.git :: topic/sh

	3cd44dcd35a6618df88c51561290dc02fb35b8e2
	(dmaengine: remove Renesas Audio DMAC peri peri)

And, this patch was posted to him in v1/v2 patch-set.
But, he couldn't apply it, because of base branch (?)
According to Simon (= SH-ARM maintainer) this patch should be taken
ARM maintainer.
http://thread.gmane.org/gmane.linux.ports.sh.devel/44657/focusD857

I can say that this removal CONFIG_RCAR_AUDMAC_PP patch has no relationship
to DMAEngine branch, because no SoC/platform is using it.
(more detail, defconfig has it, but, there is no DT settings in upstream)
So, I think you don't need to care about Vinod's branch

[PATCH 1/1] ARM: configs: remove all CONFIG_RCAR_AUDMAC_PP from ARM defconfigs

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as
Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC).
And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine.
But, in result of DMA ML discussion, 2nd DMAC was concluded that it is
not a general purpose DMAC (2nd DMAC is for Device to Device inside
sound system). Additionally, current DMAEngine can't support Device to
Device, and we don't have correct DT bindings for it at this point.
So the easiest solution for it is that move it from DMAEngine to rsnd
driver.
Audio DMAC peri peri DMAEngine is no longer needed.
