[PATCH 0/3] ASoC: rsnd: fixup Ctrl-Z + fg behavior

[Kuninori Morimoto]

Hi Mark

Current rsnd driver has strange behavior if we do
Ctrl-Z + fg, and its related operation.
These patches fix these issues.

Kuninori Morimoto (3):
  ASoC: rsnd: tidyup src->convert_rate reset timing
  ASoC: rsnd: merge rsnd_kctrl_new_m/s/e into rsnd_kctrl_new()
  ASoC: rsnd: control kctrl items acceptance anytime/runtime

[PATCH 1/3] ASoC: rsnd: tidyup src->convert_rate reset timing

[Kuninori Morimoto]

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

Current src->convert_rate will be set on .hw_param, and
be reset on .quit timing.
But, .hw_param will not be called again if user did Ctrl-Z + fg.
It should be reset on initial of .hw_param to keep its value.
Here, ctu.c already do this.
This patch solves this issue, other wise, MIXed sound will be
strange if user did like below.

Applied "ASoC: rsnd: tidyup src->convert_rate reset timing" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: tidyup src->convert_rate reset timing

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

[PATCH 3/3] ASoC: rsnd: control kctrl items acceptance anytime/runtime

[Kuninori Morimoto]

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

Current SRC/DVC/CTU adds kctrl for each device, but
some of them shouldn't set *before* playback/capture.
This patch control it more clearly

Why is there this restriction for these controls - what are they doing?

Sorry, this log is not good explanation.
Our HW can adjust its sampling rate during playback.
According to HW team, it will be used for TV or radio purpose.
They want to adjust it like 48001Hz - 47999Hz during playback.
This adjustment should be enabled during playback.
Thus, this patch ignores this adjustment *before* playback.

Best regards

The patch

   ASoC: rsnd: control kctrl items acceptance anytime/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

Subject: [PATCH] ASoC: rsnd: control kctrl items acceptance anytime/runtime

Current SRC/DVC/CTU adds kctrl for each device,
and SRC can adjust its sampling rate during playback,
thus, this feature should be enabled only *during* playback.
This patch controls it more clearly
