[PATCH 0/14] ASoC: rsnd: TDM Extend Mode support

[Kuninori Morimoto]

Hi Mark

These patch-set adds TDM Extend Mode to Renesas R-Car sound driver.
 1) -  9) tidyup / cleanup patches
10) - 14) TDM Extend Mode support

Unfortunately, our board can't use this TDM Extend Mode, because
our SoC and codec are using different style TDM.
Thus I have tested this patches on special board which doesn't have codec chip,
and I checked signal via oscilloscope.

oKuninori Morimoto (14):
       1) ASoC: rsnd: don't use normal *mod in adg.c
       2) ASoC: rsnd: add missing ADINR::CHNUM on DVC/SRC/SSIU
       3) ASoC: rsnd: add missing SRC_O_BUSIF_MODE register
       4) ASoC: rsnd: src: rename rsnd_src_soft_reset() to rsnd_src_activation()
       5) ASoC: rsnd: mix: rename rsnd_mix_soft_reset() to rsnd_mix_activation()
       6) ASoC: rsnd: dvc: rename rsnd_dvc_soft_reset() to rsnd_dvc_activation()
       7) ASoC: rsnd: src: add rsnd_src_halt()
       8) ASoC: rsnd: mix: add rsnd_mix_halt()
       9) ASoC: rsnd: dvc: add rsnd_dvc_halt()
      10) ASoC: rsnd: add rsnd_ssi_config_init()
      11) ASoC: rsnd: set SSIWSR setting on rsnd_ssi_config_init()
      12) ASoC: rsnd: ssi enables non-stereo sound
      13) ASoC: rsnd: dvc enables non-stereo sound
      14) ASoC: rsnd: add TDM Extend Mode support

[PATCH 01/14] ASoC: rsnd: don't use normal *mod in adg.c

[Kuninori Morimoto]

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

adg.c is used from ssi/src/cmd. Thus don't use confusable *mod here.
This patch rename it to ssi_mod/src_mod/cmd_mod

[PATCH 03/14] ASoC: rsnd: add missing SRC_O_BUSIF_MODE register

[Kuninori Morimoto]

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

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.

[PATCH 11/14] ASoC: rsnd: set SSIWSR setting on rsnd_ssi_config_init()

[Kuninori Morimoto]

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

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().

[PATCH 12/14] ASoC: rsnd: ssi enables non-stereo sound

[Kuninori Morimoto]

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

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.

[PATCH 14/14] ASoC: rsnd: add TDM Extend Mode support

[Kuninori Morimoto]

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

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.

Applied "ASoC: rsnd: add TDM Extend Mode support" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: add TDM Extend Mode support

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] 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: [PATCH] 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: [PATCH] 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().

Applied "ASoC: rsnd: src: rename rsnd_src_soft_reset() to rsnd_src_activation()" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: src: rename rsnd_src_soft_reset() to rsnd_src_activation()

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] 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.
