[PATCH 00/13] ASoC: add full BUSIF support

[Kuninori Morimoto]

Hi Mark
Cc: Jiada, Timo, Dragos

Dragos, Jiada, Timo added full BUSIF support,
expand TDM mode, TDM split mode and its related features
to Renesas sound driver on v4.14 base kernel.
Thank you Dragos, Jiada, Timo.

Unfortunately, I can't confirm expand TDM mode, TDM split mode
on my environment. But I could confirm/test full BUSIF support.
These patches are for it.

Dragos Tarcatu (3):
  ASoC: rsnd: add support for 16/24 bit slot widths
  ASoC: rsnd: add support for the DSP_A/DSP_B formats
  ASoC: rsnd: add support for 8 bit S8 format

[PATCH 01/13] ASoC: rsnd: add warning message to rsnd_kctrl_accept_runtime()

[Kuninori Morimoto]

From: Jiada Wang <jiada_wang@mentor.com>

Add warning message to rsnd_kctrl_accept_runtime(), when kctrl
update is rejected due to corresponding dai-link is idle.
So that user can notice the reason of kctrl update failure.

Applied "ASoC: rsnd: add support for the DSP_A/DSP_B formats" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: add support for the DSP_A/DSP_B formats

has been applied to the asoc tree at

   https://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,

&rdai->capture based on whether it is a playback or capture stream,
in __rsnd_soc_hw_rule_* functions, but this is not necessary,
rsnd_dai_stream *io handler can be get from rule->private.

This patch removes 'is_play' parameter from hw_rule function.

[PATCH 06/13] ASoC: rsnd: ssi: Fix issue in dma data address assignment

[Kuninori Morimoto]

From: Jiada Wang <jiada_wang@mentor.com>

Same SSI device may be used in different dai links,
by only having one dma struct in rsnd_ssi, after the first
instance's dma config be initilized, the following instances
can no longer configure dma, this causes issue, when their
dma data address are different from the first instance.

[PATCH 07/13] ASoC: rsnd: ssi: Check runtime channel number rather than hw_params

[Kuninori Morimoto]

From: Jiada Wang <jiada_wang@mentor.com>

The number of channel handled by SSI maybe differs from the one set
in hw_params, currently SSI checks hw_params's channel number,
and constrains to use same channel number, when it is being
used by multiple clients.

This patch corrects to check runtime channel number rather
than channel number set in hw_params.

[PATCH 08/13] ASoc: rsnd: dma: Calculate dma address with consider of BUSIF

[Kuninori Morimoto]

From: Jiada Wang <jiada_wang@mentor.com>

DMA address calculated by rsnd_dma_addr() only considers BUSIF0 so far.
But BUSIF1 ~ BUSIF7 also maybe used, in the future.

This patch updates DMA address calculations, to also consider
BUSIF number used by SSI.

One note is that we can't support SSI9-4/5/6/7 so far,
because its address is out of calculation rule.

[PATCH 09/13] ASoc: rsnd: dma: Calculate PDMACHCRE with consider of BUSIF

[Kuninori Morimoto]

From: Jiada Wang <jiada_wang@mentor.com>

PDMACHCR setting for SSI only considers BUSIF0 so far.
But BUSIF1 ~ BUSIF7 also maybe used, in the future.

This patch updates table gen2_id_table_ssiu, to also consider
BUSIF number used by SSI.

Subject: [PATCH] ASoc: rsnd: dma: Calculate PDMACHCRE with consider of BUSIF

PDMACHCR setting for SSI only considers BUSIF0 so far.
But BUSIF1 ~ BUSIF7 also maybe used, in the future.

This patch updates table gen2_id_table_ssiu, to also consider
BUSIF number used by SSI.

[PATCH 10/13] ASoC: rsnd: ssiu: Support BUSIF other than BUSIF0

[Kuninori Morimoto]

From: Jiada Wang <jiada_wang@mentor.com>

Currently only BUSIF0 is supported by SSIU, all register setting
is done only for BUSIF.

Since BUSIF1 ~ BUSIF7 has been supported, so also support
these BUSIF from SSIU.

One note is that we can't support SSI9-4/5/6/7 so far,
because its address is out of calculation rule.

[PATCH 11/13] ASoC: rsnd: ssiu: Support to init different BUSIF instance

[Kuninori Morimoto]

From: Jiada Wang <jiada_wang@mentor.com>

Currently ssiu's .init is only called once during audio stream.
But SSIU with different BUSIF, shall be initialized each time,
even they are used in the same audio stream.

This patch introduces ssiu_status for BUSIF0 to BUSIF7 in rsnd_ssiu,
to make sure same .init for different BUSIF can always be executed.

To avoid the first stopped stream to stop the whole SSIU,
which may still has other BUSIF instance running, use usrcnt to count
the usage of SSIU, only the last user of SSIU can stop the whole SSIU.

[PATCH 12/13] ASoC: rsnd: fixup not to call clk_get/set under non-atomic

[Kuninori Morimoto]

From: Jiada Wang <jiada_wang@mentor.com>

Clocking operations clk_get/set_rate, are non-atomic,
they shouldn't be called in soc_pcm_trigger() which is atomic.

Following issue was found due to execution of clk_get_rate() causes
sleep in soc_pcm_trigger(), which shouldn't be blocked.

We can reproduce this issue by following
	> enable CONFIG_DEBUG_ATOMIC_SLEEP=y
	> compile, and boot
	> mount -t debugfs none /sys/kernel/debug
	> while true; do cat /sys/kernel/debug/clk/clk_summary > /dev/null; done &
	> while true; do aplay xxx; done

This patch adds support to .prepare callback, and moves non-atomic
clocking operations to it. As .prepare is non-atomic, it is always
called before trigger_start/trigger_stop.

Generally bugfix patches like this should go at the start of the series
to make sure they don't have any dependencies on other patches and can
be applied separately and sent to Linus before the merge window.

Ahh, yes, indeed.
I'm sorry about that.

Subject: [PATCH] ASoC: rsnd: fixup not to call clk_get/set under non-atomic

Clocking operations clk_get/set_rate, are non-atomic,
they shouldn't be called in soc_pcm_trigger() which is atomic.

Following issue was found due to execution of clk_get_rate() causes
sleep in soc_pcm_trigger(), which shouldn't be blocked.

We can reproduce this issue by following
	> enable CONFIG_DEBUG_ATOMIC_SLEEP=y
	> compile, and boot
	> mount -t debugfs none /sys/kernel/debug
	> while true; do cat /sys/kernel/debug/clk/clk_summary > /dev/null; done &
	> while true; do aplay xxx; done

This patch adds support to .prepare callback, and moves non-atomic
clocking operations to it. As .prepare is non-atomic, it is always
called before trigger_start/trigger_stop.

[PATCH 13/13] ASoC: rsnd: merge .nolock_start and .prepare

[Kuninori Morimoto]

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

Main purpose of .nolock_start is we need to call
some function without spinlock.
OTOH we have .prepare which main purpose is
called under atomic context.
Then, it is called without spinlock.

In summary, our main callback init/quit, and start/stop
are called under "atomic context and with spinlock".
And some function need to be called under
"non-atomic context or without spinlock".
Let's merge .nolock_start and prepare to be more clear code.
Then, let's rename nolock_stop to cleanup

Applied "ASoC: rsnd: merge .nolock_start and .prepare" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: merge .nolock_start and .prepare

has been applied to the asoc tree at

   https://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.

Subject: [PATCH] ASoC: rsnd: merge .nolock_start and .prepare

Main purpose of .nolock_start is we need to call
some function without spinlock.
OTOH we have .prepare which main purpose is
called under atomic context.
Then, it is called without spinlock.

In summary, our main callback init/quit, and start/stop
are called under "atomic context and with spinlock".
And some function need to be called under
"non-atomic context or without spinlock".
Let's merge .nolock_start and prepare to be more clear code.
Then, let's rename nolock_stop to cleanup
