[PATCH 0/11] ASoC: rsnd: cleanup SSI multi mode and sequence

[Kuninori Morimoto]

Hi Mark

Current rsnd driver is supporting many features, and now we are
confirming these register settings sequence.
These patches fixup not good sequence (and bug)

Kuninori Morimoto (11):
      ASoC: rsnd: rename RSND_DVC_CHANNELS to RSND_MAX_CHANNELS
      ASoC: rsnd: setup SRC_ROUTE_MODE0 before SRC_SRCIR
      ASoC: rsnd: indicates status failed SSI
      ASoC: rsnd: SSI function parameter uses "mod" instead of "ssi"
      ASoC: rsnd: fixup forever loop bug on SSI
      ASoC: rsnd: add missing .irq callback for DMA
      ASoC: rsnd: tidyup SSI init/start sequence
      ASoC: rsnd: Parent SSI attach is not needed if not clock master
      ASoC: rsnd: move rsnd_ssi_irq() position
      ASoC: rsnd: judge multi SSI in runtime
      ASoC: rsnd: judge work SSI in runtime

[PATCH 02/11] ASoC: rsnd: setup SRC_ROUTE_MODE0 before SRC_SRCIR

[Kuninori Morimoto]

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

SRC_ROUTE_MODE0 determines whether to use SRC.
Thus, it should be setup before SRC_SRCIR.

[PATCH 05/11] ASoC: rsnd: fixup forever loop bug on SSI

[Kuninori Morimoto]

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

commit b5b442abd9 ("ASoC: rsnd: add .irq callback")
added .irq support, and it cares both parent SSI and normal SSI.
But it should care only normal SSI. Otherwise SSI might be
forever loop if SSI is used as both parent SSI and normal SSI
(= 2 users), and if under/over run error happen. Because irq disable
do nothing in such case. This patch solve this issue.

[PATCH 07/11] ASoC: rsnd: tidyup SSI init/start sequence

[Kuninori Morimoto]

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

SSI want to have SSIWSR settings and SSICR settings without EN bit
when init, and SSICR EN bit only when start timing.
Otherwise, SSI output signal might be unstable.

[PATCH 08/11] ASoC: rsnd: Parent SSI attach is not needed if not clock master

[Kuninori Morimoto]

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

Parent SSI is needed if it is PIN sharing and clock master,
otherwise, not needed. But, whether clockk master is judged on
.set_fmt, thus, it can't call rsnd_ssi_parent_attach() on .probe.

Now, .pcm_new will be called after .set_fmt, so this patch reuses it
at this point.

[PATCH 10/11] ASoC: rsnd: judge multi SSI in runtime

[Kuninori Morimoto]

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

Current rsnd supports multi SSI (maximum 4 SSI for 8ch),
and, it should determine whether using each SSI or not in runtime.
Current judgement is vague, and had broken by
c308abe45e2("ASoC: rsnd: rsnd_ssi_is_multi_slave() macro uses
rsnd_ssi_multi_slaves()")
This patch makes clean it, and solve this issue.

[PATCH 11/11] ASoC: rsnd: judge work SSI in runtime

[Kuninori Morimoto]

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

Current rsnd supports multi SSI (maximum 4 SSI for 8ch),
and, it should determine whether using each SSI or not in runtime.
All SSIs are not used even if there are 4 SSI in case of stereo.

Current driver setups un-used SSI in such case. It is no problem,
but not needed. This patch judges it.

Applied "ASoC: rsnd: judge work SSI in runtime" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: judge work SSI in runtime

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

Applied "ASoC: rsnd: Parent SSI attach is not needed if not clock master" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: Parent SSI attach is not needed if not clock master

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: Parent SSI attach is not needed if not clock
 master

Parent SSI is needed if it is PIN sharing and clock master,
otherwise, not needed. But, whether clockk master is judged on
.set_fmt, thus, it can't call rsnd_ssi_parent_attach() on .probe.

Now, .pcm_new will be called after .set_fmt, so this patch reuses it
at this point.

SSI want to have SSIWSR settings and SSICR settings without EN bit
when init, and SSICR EN bit only when start timing.
Otherwise, SSI output signal might be unstable.

Subject: [PATCH] ASoC: rsnd: fixup forever loop bug on SSI

commit b5b442abd9 ("ASoC: rsnd: add .irq callback")
added .irq support, and it cares both parent SSI and normal SSI.
But it should care only normal SSI. Otherwise SSI might be
forever loop if SSI is used as both parent SSI and normal SSI
(= 2 users), and if under/over run error happen. Because irq disable
do nothing in such case. This patch solve this issue.

Applied "ASoC: rsnd: setup SRC_ROUTE_MODE0 before SRC_SRCIR" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: setup SRC_ROUTE_MODE0 before SRC_SRCIR

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: setup SRC_ROUTE_MODE0 before SRC_SRCIR

SRC_ROUTE_MODE0 determines whether to use SRC.
Thus, it should be setup before SRC_SRCIR.

The channels number is not only for DVC. Let's rename it.
