Subject: ASoC: rsnd: add dma.c for Audio DMAC / Audio DMAC peri peri

Renesas sound driver had been assumed that Audio DMAC /
Audio DMAC peri peri are implemented by DMAEngine. But, result of DMA
ML discussion, it was concluded that it is not a general purpose DMAC.
And it should be moved from current DMAEngine to rsnd driver.
So, Audio DMAC peri peri become non DMAEngine.

OTOH, ALSA SoC has soc-generic-dmaengine-pcm implementation. but it
seems difficult to use this generic implementation on rsnd driver at
this point, since it needs to fallback to PIO mode if DMA can't use.
and additionally it needs 2 DMAC (= Audio DMAC / Audio DMAC peri peri).
These are not "generic" feature.

Of course I will try to use this generic dmaengine in the future somehow,
but just use current style at this point until it can formally use 2 DMACs.
This patch adds new dma.c and moves current dma code to dma.c from core.c.

Subject: ASoC: rsnd: move rsnd_gen_dma_addr() from gen.c to dma.c

Now, we have dma.c for Audio DMAC / Audio DMAC peri peri.
rsnd_gen_dma_addr() should go there.

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
Date: Fri, 20 Feb 2015 10:27:12 +0000
Subject: ASoC: rsnd: enable to care 1st / 2nd DMAC on rsnd_dma_xxx()

rsnd driver needs to care about Audio DAMC (via DMAEngine),
Audio DMAC peri peri (via local method) on rsnd driver.
This patch adds new rsnd_dma_ops and care it.

Subject: ASoC: rsnd: add Audio DMAC peri peri support rework

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 is controlled from sound driver without DMAEngine
by this patch.

DMAEngine for Renesas R-Car driver is used only for Audio DMAC now.
rsnd_dma::addr was added to support Audio DMAC peri peri,
but it is no longer needed. Let's remove it

implemented as local code. These 2 DMACs are never shared.
We can use union for these.

Subject: ASoC: rsnd: enable rsnd_ssi_use_busif() for DMA

Renesas R-Car sound driver uses SSI, but the DMA interfaces are
SSI/SSIU. This interface is based on SSI/SRC/DVC connection.
And DMA function needs to know which interface is used somehow.
This patch enables rsnd_ssi_use_busif() for DMA.

Subject: ASoC: rsnd: 1st DMAC dma-names cares subnode

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.

dma-names on DT was implemented as no difference between 1st / 2nd
DMAC's, since rsnd had assumed that both DMACs are implemented as
DMAEngine. That style was "src_dst". But now, 2nd DMAC was implemented
as non DMAEngine, and it doesn't need dma-names anymore. So, this
dma-names rule is no longer needed.

And additionally, dma-names was assumed that it has all
(= SSI/SSIU/SRC/DVC) nodes under sound node.

In upstream code, no SoC/platform is supporting DMA for rsnd driver yet.
This means there is no compatible issue if this patch changes
dma-names's rule of DT.

This patch assumes dma-names for 1st DMAC are tx/rx base, and listed
in each SSI/SRC/DVC subnode
ex)
	rcar_sound,dvc {
		dvc0: dvc@0 {
			dmas = <&audma0 0xbc>;
			dma-names = "tx";
		};
	...

	rcar_sound,src {
		src0: src@0 {
			...
			dmas = <&audma0 0x85>, <&audma1 0x9a>;
			dma-names = "rx", "tx";
		};
	...

	rcar_sound,ssi {
		ssi0: ssi@0 {
			...
			dmas = <&audma0 0x01>, <&audma1 0x02>, <&audma0 0x15>, <&audma1 0x16>;
			dma-names = "rx", "tx", "rxu", "txu";
		};
	...

Subject: ASoC: rsnd: recover PIO mode for new dma interface

Renesas sound driver needs 1st/2nd DMA interface,
and 1st DMA is using DMAEngine, and 2nd is using local method now.
2nd DMA had been DMAEngine, but it was moved to local method by previous
patchset. But then, it lost PIO mode fallback when probe.
this patch recovers it.

Renesas sound driver needs SSI/SRC/DVC regmaps, but it didn't have
regmap_config::name for devm_regmap_init_mmio().
Thus, debugfs initialization code tried to use same driver name
many times, and failed.
This patch adds eacy own name for regmap_config::name

Subject: ASoC: rsrc-card: add Renesas sampling rate convert sound card support

Renesas sound card has "sampling rate convert" feature which
should be implemented via DPCM.
But, sound card driver point of view, it is difficult to add
this DPCM feature on simple-card driver. Especially, DT binding
support is very difficult.

This patch implements DPCM feature on DT as Renesas specific sound card.
This new driver is copied from current simple-card driver.
Main difference between simple-card and this driver are...
 1. removed unused feature from simple-card
 2. removed driver named prefix from DT property
 3. CPU will be FE, CODEC will be BE with snd-soc-dummy
 4. it supports sampling rate convert via .be_hw_params_fixup
 5. board specific routing is implemented in driver

Subject: ASoC: rsrc-card: add .be_hw_params_fixup support for convert rate

Current rsnd-dpcm-card is supporting DPCM FE/BE sound card.
This patch adds .be_hw_params_fixup and enabled sampling convert rate.

Subject: ASoC: rsnd: remove useless debug message

This patch removes useless debug message. especially some kind of
"probed" message will be printed from core.c if it has #define DEBUG

Subject: ASoC: rsnd: add DPCM based sampling rate convert

This patch supports DPCM based sampling rate convert on Renesas sound
driver. It assumes...
 1. SRC is implemented as FE
 2. BE dai_link supports .be_hw_params_fixup

Subject: ASoC: rsnd: add Synchronous SRC mode

Renesas R-Car sound SRC (= Sampling Rate Converter) has
Asynchronous/Synchronous SRC mode. Asynchronous mode is already
supported via DPCM. This patch adds Synchronous mode on it.

The condition of enabling Synchronous mode are
- SoC is clock master
- Sound uses SRC
- Sound doesn't use DVC
- Sound card uses DPCM (= rsrc-card card)

	aplay xxx.wav &

Subject: ASoC: rnsd: fix build regression without CONFIG_OF

The r-car sound driver only works when CONFIG_OF is set, and
after a recent change has a compile-time dependency as well:

sound/built-in.o: In function `rsnd_dma_request_channel':
:(.text+0x9fb84): undefined reference to `of_dma_request_slave_channel'

This could be fixed either by adding a static inline wrapper
for the function, or by adding a Kconfig dependency. This
implements the second approach, which seems appropriate
because the driver in fact has a hard dependency.
