#1425625 — [PATCH 0/4] ASoC: tpa6130a2: Add support for multiple instances

FromHelen Koike <helen.koike@collabora.co.uk>
Date2016-06-18 05:40 +0200
Subject[PATCH 0/4] ASoC: tpa6130a2: Add support for multiple instances
Message-ID<rLfgZ-74e-3@gated-at.bofh.it>
The current tpa6130a2 driver supports only a single instance.
This patch series add support for multiple instances by removing the global
variable that holds the instance.
This is performed by using the component API, regmap, the
snd_soc_{info,put,get}_volsw API and DAPM.

This patch series also touches code from the Nokia RX51 which I didn't tested (as
I am testing the tpa6130a2 in another board that is not upstream).
I would appreciate is if someone who possesses the Nokia RX51 (n900) could please
test the code.

This patch series is based on git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next
Available at https://git.collabora.com/cgit/user/koike/linux.git/log/?h=sound/review/tpa6130a2

I had a look at the rx51 parts and will test later/tomorrow.
From looking at the source code: You can also remove the
"../codecs/tpa6130a2.h" include from rx51.c.

Ok, here are some notes (I used the git branch you provided). First
of all kernel messages contain:

[    4.217163] ALSA: Control name 'TPA6130A2 TPA6130A2 Headphone Playback Volum' truncated to 'TPA6130A2 TPA6130A2 Headphone Playback Volu'

Next here is a amixer output diff:

If I remember correctly, the reduced playback limit up to 42 is
important on N900, since hardware can be destroyed. It may have been
another control, though. Also the capture channel looks wrong.

Last but not least: Audio output doesn't work, but works on a kernel
without these changes.

#1429903 — Applied "ASoC: tpa6130a2: Use snd soc volsw functions" to the asoc tree

FromMark Brown <broonie@kernel.org>
Date2016-06-23 16:40 +0200
SubjectApplied "ASoC: tpa6130a2: Use snd soc volsw functions" to the asoc tree
Message-ID<rNdXr-2Tn-11@gated-at.bofh.it>
In reply to#1426839
The patch

   ASoC: tpa6130a2: Use snd soc volsw functions

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

#1426840 — [PATCH v2 4/5] ASoC: tpa6130a2: Add DAPM support

FromHelen Koike <helen.koike@collabora.co.uk>
Date2016-06-20 19:30 +0200
Subject[PATCH v2 4/5] ASoC: tpa6130a2: Add DAPM support
Message-ID<rMbbk-2Hq-3@gated-at.bofh.it>
In reply to#1425697
Add DAPM support and updated rx51 accordingly.
As a consequence:
- the exported function tpa6130a2_stereo_enable is not needed anymore
- the mutex is dealt in the DAPM
- the power state is tracked by the DAPM

Changes since v1:
- Replace

	+	{"TPA6130A2 HPRIGHT", NULL, "RLOUT"}

	by

	+       {"TPA6130A2 LEFTIN", NULL, "LLOUT"},
	+       {"TPA6130A2 RIGHTIN", NULL, "RLOUT"},
- Add tested-by and reviewed-by from Sebastian
- Add struct device dev* in struct tpa6130a2_data and pass data instead
of dev to tpa6130a2_power function
- remove #include "../codecs/tpa6130a2.h" in rx51.c

I added these changes above and kept your tested-by and reviewed-by, 
could you please confirm that I can keep them? As I changed more things 
then you suggested.

Thank you

The changes look fine to me, the new patchset works on N900.

checkpatch.pl should complain about this. Kernel code style is if one branch
has branches the other has to have it as well.

Weird, checkpatch.pl doesn't complain. I'll add the braces in v3, thank

#1429898 — Applied "ASoC: tpa6130a2: Register component" to the asoc tree

FromMark Brown <broonie@kernel.org>

SubjectApplied "ASoC: tpa6130a2: Register component" to the asoc tree
Message-ID<rNdXr-2Tn-5@gated-at.bofh.it>
In reply to#1426843
The patch

   ASoC: tpa6130a2: Register component

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

#1426849 — [PATCH v2 0/5] ASoC: tpa6130a2: Add support for multiple instances

FromHelen Koike <helen.koike@collabora.co.uk>
Date2016-06-20 19:30 +0200
Subject[PATCH v2 0/5] ASoC: tpa6130a2: Add support for multiple instances
Message-ID<rMb1E-2DX-49@gated-at.bofh.it>
In reply to#1425697
The current tpa6130a2 driver supports only a single instance.
This patch series add support for multiple instances by removing the global
variable that holds the instance.
This is performed by using the component API, regmap, the
snd_soc_{info,put,get}_volsw API and DAPM.

This patch series also touches code from the Nokia RX51 which I didn't tested (as
I am testing the tpa6130a2 in another board that is not upstream).
I would appreciate is if someone who possesses the Nokia RX51 (n900) could please
test the code.

This patch series is based on git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next
Available at https://git.collabora.com/cgit/user/koike/linux.git/log/?h=sound/review/tpa6130a2

  ASoC: tpa6130a2: Register component
