Subject: ASoC: rsnd: DMA become SSI/SRC member

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.

Current rsnd_mod is member of rsnd_mod. But the DMA user is only
SSI/SRC. This DMA will be implemented as module. As 1st step, DMA
become SSI/SRC member by this patch.

DMA will be implemented as module. Then each rsnd_dma_ops will be
rsnd_mod_ops. But current rsnd_dma_ops::init means "DMA attach".
This patch removes .init from rsnd_dma_ops, and renames
rsnd_dma_init() to rsnd_dma_attach()

Subject: ASoC: rsnd: enable to use rsnd_dai_connect() from each mod

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.

DMAC/SSIU/SSI-parent/CMD will be implemented as module, but these are
not customer controlled module. These should be automatically install
to system. Because of this, rsnd_dai_connect() should be called from
each mod. SSI can be very special, because it will be installed as
SSI-parent / SSI-child. Thus, new rsnd_dai_connect() has type parameter
which should be mod->type except SSI-parent

Subject: ASoC: rsnd: remove all modules when PIO fallback

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.

Subject: ASoC: rsnd: rsnd_dai_stream has each mod's status insted of rsnd_mod

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.

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.

Subject: ASoC: rsnd: Don't stop HW even if a large number of errors occur

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.

Subject: ASoC: rsnd: avoid pointless loop in rsnd_mod_interrupt()

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.

Subject: ASoC: rsnd: use mod base common method on DMA phase1

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.

DMA will be implemented as module. Then rsnd_dma will be mod base.
This patch makes rsnd_dma mod base, but still not yet completely
finished. This mod is not yet installed to system at this point.

Subject: ASoC: rsnd: use mod base common method on DMA phase2

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.

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.
This is prepare for final merge

Subject: ASoC: rsnd: use mod base common method on CMD

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 CMD mod base common method

Subject: ASoC: rsnd: use mod base common method on SSIU

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

Subject: ASoC: rsnd: use mod base common method on SSI-parent

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 SSI parent mod base common method

If the "clock-frequency" DT property is not found, req_rate is used
uninitialized, and the "audio_clkout" clock will be created with an
arbitrary clock rate.

This uninitialized kernel stack data may leak to userspace through
/sys/kernel/debug/clk/clk_summary, cfr. the value in the "rate" column:

Subject: ASoC: rsnd: call clk_prepare()/clk_enable() for AUDIO_CLKx

ADG can output AUDIO_CLKOUTx, and these are generated from
AUDIO_CLKx. Thus we need to call clk_prepare()/clk_enable()
for AUDIO_CLKx.

Subject: ASoC: rsnd: ssi: 24bit data needs right-aligned settings

Data left/right aligned is controlled by PDTA bit on SSICR.
But default is left-aligned. Thus 24bit sound will be very small sound
without this patch.

Subject: ASoC: rsnd: remove Gen1 support from SRC

This patch removes SRC Gen1 support which has no user on upstream.
Historically, SRC Gen1 was created as prepare for SRC Gen2 support.
It works well for Gen2 support, but Gen1 is not same as Gen2.
So now, Gen1 support is no longer needed. Thanks Gen1 and Bye-bye.

Subject: ASoC: rsnd: cleanup RSND_REG_xxx

SRC Gen1 support was removed. Current rsnd driver is sharing Gen1/Gen2
register index to reduce memory, but there is no effect anymore.
Let's remove share definition and merge RSND_REG_xxx

Subject: ASoC: rsnd: remove platform boot support from core.c

No board is using Renesas sound driver via platform boot now.
This means all user is using DT boot. Platform boot support is
no longer needed. But, it strongly depends on platform boot style.
This patch removes platform boot support from core.c

Subject: ASoC: rsnd: remove platform boot support from ssi.c

No board is using Renesas sound driver via platform boot now.
This means all user is using DT boot. Platform boot support is
no longer needed. But, it strongly depends on platform boot style.
This patch removes platform boot support from ssi.c

No board is using Renesas sound driver via platform boot now.
This means all user is using DT boot. Platform boot support is
no longer needed. But, it strongly depends on platform boot style.

Subject: ASoC: rsnd: remove struct platform_device from probe/remove parameter

Current Renesas sound driver requests struct platform_device on
probe/remove for each modules. But driver can get it by
rsnd_priv_to_pdev(). This patch removes unnecessary parameter

Subject: ASoC: rsnd: indicate register name for debug

Current rsnd driver is indicating how to use regmap debug method
on gen.c comment area.
regmap debug method indicates address and value, but rsnd driver is
using too many IPs (SSI/SSIU/SRC/CTU/MIX/DVC/CMD), and address.
Thus, we would like to know more useful information for debugging.
This patch indicates address name for debugging.

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()

Subject: 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.

Subject: ASoC: rsnd: set SSIWSR setting on rsnd_ssi_config_init()

It will have TDM settings on SSIWSR. Actually, we would like to set
it on rsnd_ssi_config_init(), but we can't. Because SSI might be used
as clock master (It doesn't need to call rsnd_ssi_config_init() when
clock master mode).
This patch adds new ssi->wsr and set it on rsnd_ssi_start().

Subject: ASoC: rsnd: ssi enables non-stereo sound

Current SSI is assuming that the sound is always stereo. But, SSI needs
to calculate its frequency when master mode. Then This frequency depends
on each SSI's slots, and TDM mode (= TDM Extend Mode, TDM split Mode,
TDM Multichannel Mode).
This patch enables to use non-stereo sound.

Subject: ASoC: rsnd: add TDM Extend Mode support

Renesas R-Car can out TDM by
1) 6ch x 1 DAI as TDM Extend Mode
2) 2ch x 4 x 1 DAI as TDM split Mode
3) 2ch x 3 DAI or
   2ch x 4 DAI as TDM Multichannel Mode

This patch adds 1) TDM Extend Mode. Because of HW design,
this 6ch data will be outputed via 8ch data width.

Subject: ASoC: rsrc-card: Remove support for setting differing DAI formats

1efb53a220 ("ASoC: simple-card: Remove support for setting differing
DAI formats") removed set_fmt support from simple-card.
rsrc-card follows same style, because it is based on simple-card.

Subject: ASoC: rsrc-card: tidyup dai format for DPCM

rsrc-card is DPCM supported version of simple-card. Thus it has similar
DT format. OTOH, snd_soc_dai_link requests cpu/codec, but one of them
will be snd-soc-dummy in DPCM case, and DPCM requests frontend/backend
dai_link. This means it might have multi backend/codec.
And, SND_SOC_DAIFMT_xxx is based on "codec". Because of these
difference, current rsrc card can't detect correct dai_fmt.
This patch detect correct dai fmt from 1st "codec".

Renesas sound driver has rsnd_get_adinr_bit/chan() functions.
It is assuming _bit() returns ADINR :: OTBL,
and _chan() returns ADINR :: CHNUM.
Current _bit() returns both OTBL and CHNUM. This patch fixup it.

(it returns 8 if total 6 channels). This will be used on SSI multi
channel support too (It will return 2 if total 6 channels with 3 SSI).
But, it is using confusable naming.
This patch changes rsnd_get_slot_rdai() -> rsnd_get_slot(),
rsnd_get_slot_extend() -> rsnd_get_slot_width()

Subject: ASoC: rsnd: add rsnd_set_slot() / rsnd_get_slot_num()

TDM will use 6 or 8 slots on 1 SSI, and Multi channel will use
6 or 8 slots on few SSI (each SSI uses 2 slots).
Thus, this adds new slot control functions which can be prepare
for Multi channel support.

Subject: ASoC: rsnd: add Multi channel support

This patch adds Multi channel support on Renesas R-Car sound.
This patch is tested on Salvator-X board, but it can't use
Multi channel, because supported format is different between
codec chip and R-Car.
Thus, it was tested on board which doesn't mount codec chip,
with oscilloscope.
