bf4e8d7c37 ASoC: rsnd: add missing SRC_O_BUSIF_MODE register
SRC_BUSIF_MODE has both IN/OUT register. Current src driver sets
IN register only. This patch sets missing OUT register.
IN/OUT register are using default setting, so, there is no
HW effect.

8cc225f713 ASoC: rsnd: tidyup semantics of rsnd_src_record_error()
rsnd_src_error_record() should recorde error, but it clears error too.
this patch fixes up semantic of rsnd_src_error_record that it records
error but doesn't clear error.
And this patch renames
rsnd_src_error_clear()  to rsnd_src_status_clear()
rsnd_src_error_record() to rsnd_src_record_error()

No board is using Renesas sound driver via platform boot now.

invert issue. But it will stop HW if too many error happen.
But if it stops on HW, other side under/over flow happen. OTHA, it will
be forever loop interrupt if something strange error happen on
HW/driver without escape route of large number error.

To avoid this issue, it indicates error message if large number error
occur, and disables error interrupt.

4362495734 ASoC: rsnd: Announce for removing Gen1 SRU support
Gen1 SRU support was created for preparation of Gen2 SRC support,
but no-one is using this feature (sampling rate convert) on Gen1.
BockW had used SRU before, but it was pass through mode.
This means it is same as SSI. And BockW "platform base" code was
removed from upstream code. It is now supported via DT, but it doesn't
use SRU. More detail, r8a7778.dtsi has "rcar_sound,src" entry, but
no-one is using this feature today. SRU probing has no relation to this
removing. This means there is no effect for DT compatibility, no issues
on upstream kernel.

Gen2 SRC was created from Gen1 SRU, these are similar but not same IP.
Keeping Gen1 SRU in current driver is a little bit difficult,
and no-one is using it today. Gen1 sound is still supported via SSI.
Gen1 SRU support will be removed in the next kernel version.
This patch announces it.

4689032b11 ASoC: rsnd: tidyup data align position
Sound L/R order of SSI is different from Linux sound data order.
So current rsnd driver is using DALIGN (= data align) to exchange data
align on SSIU. OTOH, CMD/SRC/SSIU have DALIGN register. Now inverted
sound volume will be exchanged if user used volume control on DVC.
Because SSIU which exchanges data align is located after DVC.

	MEM -> SRC -> DVC -> SSI

This patch exchanges data align SRC if possible

2099bc8eb0 ASoC: rsnd: rsnd_mod has rsnd_priv
Each Renesas sound mod (= SSI/SRC/DVC) might be called from many paths
if it supports MIXer. In such case, mod <-> io is no longer 1:1
relationship. This means we can't use rsnd_mod_to_io() in SSI/SRC/DMA
interrupt handler. In such case, we need to check all io in interrupt
handler, and then, "priv" is needed.
This patch adds rsnd_priv pointer in rsnd_mod for prepare it.

02299d9875 ASoC: rsnd: spin lock for interrupt handler
Renesas R-Car driver interrupt handler was not locked before.
But now, SSI/SRC interrupt handler calls restart function
which should be called under spin lock.

43cb6954f8 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)

2f78dd7f40 ASoC: rsnd: call clk_prepare/unprepare() in probe/remove
clk_prepare_enable()/clk_disable_unprepare() uses mutex inside,
in concretely clk_prepare()/clk_unprepare().And it uses __schedule().
Then, raw_spin_lock/unlock_irq() is called, and it breaks Renesas
sound driver's spin lock irq.
This patch separates thesse into clk_prepare()/clk_unprepare() and
clk_enable/clk_disable. And call clk_prepare()/clk_unprepare() from
probe/remove function. Special thanks to Das Biju.

72adc61f46 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";
		};
	...
