Renesas sound needs many devices
(SSI/SSIU/SRC/CTU/MIX/DVC/CMD/AudioDMAC/AudioDMACpp).
SSI/SRC/CTU/MIX/DVC are implemented as module.
SSI parent, SSIU are implemented as part of SSI
CMD is implemented as part of CTU/MIX/DVC
AudioDMAC/AudioDMACpp are implemented as part of SSI/SRC
It is nice sense that these all devices are implemented as mod.
This patch makes SSIU mod base common method

DMA will be implemented as module. Then rsnd_dma_ops will be rebased
to rsnd_mod_ops, but these are similar, but different function.
This patch modify rsnd_dma_ops same style as rsnd_mod_ops.

Current Renesas sound driver doesn't have 1:1 relationship between
stream <-> mod because it is supporting MIX. Because of this reason
rsnd_mod_interrupt() is searching correspond mod by for loop.
But this loop is not needed, because each mod has own type.
This patch avoid pointless loop by using mod->type.
This patch is good for SSI-parent support, because stream might have
2 SSI as SSI-parent/child. SSI interrupt handler will be called twice
if stream has SSI-parent without this patch.

Current SSI/SRC restarts HW if under/over flow happened to avoid L/R
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.

Current rsnd is controling each mod's status on mod. But it was not
good design for SSI, because stream might has SSI-parent.
In such case, it can't play/capture in same time, because SSI-parent
is used as normal SSI in other stream, but it shares same status.
To avoid this issue each mod's status is controlled by rsnd_dai_stream
instead of rsnd_mod.

Current Renesas sound is supporting PIO fallback if it can't use DMA.
In such case, it should remove all attached modules, but current driver
is missing about CTU/MIX. Because current implement requests
specific mod for remove.
To avoid same things in future, this patch removes all mods,
and re-connects SSI when PIO fallback case.

ASoC: Updates for v4.4
Not much core work here, a few small tweaks to interfaces but mainly the
changes here are driver ones. Highlights include:
- Updates to the topology userspace interface
- Big updates to the Renesas support from Morimoto-san
- Most of the support for Intel Sky Lake systems.
- New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10,
Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825 and Rockchip

Current rsnd_dai_call returns immediately if rsnd_mod_call return fail.
Thus, each callback-count can be unbalanced for example .init was OK,
start was OK, but, .stop was not OK. This case .quit should be called
but isn't called. And, rsnd_dai_stream_quit() also not be called.
rsnd_dai_call() should call all .stop/.quit eventhough it returns error.

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.

Since commit 3d7608e4c169af03 ("ARM: shmobile: bockw: remove legacy
board file and config"), Renesas R-Car SoCs are only supported in
generic DT-only ARM multi-platform builds. The driver doesn't need to

Renesas sound has SSI/SRC/DVC/MIX/ADG modules, and these have original
register mapping. Thus this driver is using regmap field, and each module
is using it based on each module ID.
Sometimes, each module needs other module to controlling. but current each
function is using just "mod" as parameter name. This is confusable.
For example, if SSI0 and SRC2 are connected, and if SRC module function
has bug of module access, and if it needs to control connected SSI,
SRC function will access to SSI2 (It should access to SSI0, but it uses
SRC's ID 2). This is easy to happen in current driver style.
To avoid this kind of confusable trouble, this patch adds module confirm
macro for debug purpose.
