To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Move AKM CODECs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-
o ak4535: set_bias_level() has to perform mute IO directly rather than via
ak4535 mute since struct codec no longer contains dai.

From: Liam Girdwood @ 2010-06-25 17:52 UTC (permalink / raw)
To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Move codecs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-
o cs42151 and cs4270: set_dai_sysclk() - we no longer change static _driver_
rates on clock changes (as the driver can be used by other cs24xx codec
devices). The codec device rate is checked at hw_params() time.

Move CODECs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-

To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Move TI CODECs to multi-component
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-
o tlv320aic3x: no more "setup_data" from ASoC machine drivers, platform data
must be set in one place only. Moved platform defs out into platorm header.

Hello Liam,
I'm on holiday, and I have limited access to e-mail, but I did taken a brief look at the series..
I have few question:
Is the support for the former codec->idle_bias_off is gone? This patch removes it from the
tlv320dac33, and t2l4030 codec drivers.
I'm not really sure about the restructure of the tlv320dac33 driver:
- The codec ID register read has been removed, which is really useful, and it is going to be
used to enable/disable features of DAC33 based on the ID.
- Originally the codec was off by default, now it is on all the time.
- What is the reason to move the IRQ, GPIO, and regulator request from the i2c_probe to soc_probe?
Some of these valid for the twl4030 codec as well (especially the idle_bias_off support).
I don't claim, that I have checked all the patches, and changes, but at least with the tlv320dac33,
and twl4030 codec drivers I can see some unwanted (for me) PM related regressions.
Are these removals intentional?
Thanks,
Peter

Subject: [alsa-devel] [RFC 04/16] ASoC: multi-component - TI CODECs
Move TI CODECs to multi-component
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-
o tlv320aic3x: no more "setup_data" from ASoC machine drivers, platform data
must be set in one place only. Moved platform defs out into platorm header.

No, that is still present - it's an error in the conversion (probably
caused by forward porting changes from prior to the update I guess).

So, the theory here is that when you've got both I2C and SPI on a single
CODEC all the basic setup code tends to be identical over all buses (as
it is with the current register() functions. Personally I do find this
a bit strange since it feels better to have the driver check for all the
things it needs before it has the subsystem go and try to do broader
setup work but it does do the code sharing job.

Nope, this can all be explained my merge issues since both these codecs
did go though a lot of churn in the last few months. I'll fix up soon.

Hi Liam,
For the AIC3x codec I saw that sysfs entry was missing. Is the malloc()to be done in the evm file somewhere?

Moving to multi-component model.
Since all codecs are regular kernel devices now (with platform data) is
of-simple still required ? If not, this file will be removed.

Moved generic codecs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.

Move CODECs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-
o cx20442: tty hangup now performed in codec remove() rather than machine
remove() since codec device is not now available at machine remove().

To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Moved Wolfson WM85xx CODECs to multi-component model
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.

From: Liam Girdwood @ 2010-06-25 17:52 UTC (permalink / raw)
To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Moved Wolfson WM87xx CODECs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-
o wm8753: dai mode configuration now modifies private data to store mode.

From: Liam Girdwood @ 2010-06-25 17:52 UTC (permalink / raw)
To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Moved to Wolfson CODECs multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.

From: Liam Girdwood @ 2010-06-25 17:52 UTC (permalink / raw)
To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Move Wolfson CODECs to multi-component model
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-
o wm8960: codec device no longer has set_bias(), so func moved to private data.

From: Liam Girdwood @ 2010-06-25 17:52 UTC (permalink / raw)
To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Move Wolfson CODECs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-
o wm8993: set_fll() needs to be accessed from both codec and dai
device context, so wrapper added to acces from dai context.

From: Liam Girdwood @ 2010-06-25 17:53 UTC (permalink / raw)
To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Move to Wolfson CODECs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-
o wm8994: set_fll() needs to be accessed from both codec and dai
device context, so wrapper added to acces from dai context.

From: Liam Girdwood @ 2010-06-25 17:53 UTC (permalink / raw)
To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Moved Wolfson WM90xx CODECs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.

From: Liam Girdwood @ 2010-06-25 17:53 UTC (permalink / raw)
To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Move Wolfson AudioPlus CODECs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.

From: Liam Girdwood @ 2010-06-25 17:53 UTC (permalink / raw)
To: alsa-devel; +Cc: Mark Brown, Liam Girdwood
Move Wolfson WM97xx AC97 CODECs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform device (non MFD codecs only)
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
o codec cache can now be malloc()ed by core.
