[REQUEST]
This patch series intends to "Enable Greybus Audio codec driver"
existing in the staging tree. I have shared the original patch series with
Greybus-Dev mailing list and as per the suggestion from Alexandre, I'm
also interested to push Greybus Audio to sound soc tree. Thus, now I'm
resending it to ASoc maintainers for review.
Following is the top level SW design for GB Codec driver and GB Audio
modules.
+--------------+
+-------------->+GBA Module 1 |
| +--------------+
+-----------------------+
| | |
| | Greybus | +--------------+
| SND SOC | Audio +-------------->+GBA Module 2 |
| Framework | Codec | +--------------+
| | Driver |
| | |
+-----------------------+ +--------------+
+-------------->+GBA Module N |
+--------------+
Patch 5 contains the changes to provide helper APIs to link DAPM DAI widgets
for the module added and remove/free component controls for the module removed
dynamically. Eventually, I propose to extend snd_soc_xxx APIs for this
purpose.
Kindly share your inputs.
[COVER LETTER]
The existing GB Audio codec driver is dependent on MSM8994 Audio driver.
During the development stage, this depdency was configured due to
various changes involved in MSM Audio driver to enable addtional codec
card and some of the changes proposed in mainline ASoC framework.
However, these are not the real dependencies and some of them can be
easily removed.
The folowing patch series includes the changes to resolve unnecessary
depedencies and make the codec driver functional with the latest kernel.
Patch 1,2: Incudes jack framework related changes.
Patch 3,4,5: Resolves compilation error observed with the latest kernel and
also provides helper APIs required to allow dynamic addition/removal of
modules.
Patch 6: Finally provides config options and related Makefile changes to
enable GB Codec driver.
Thanks to Alexandre for raising the headsup [1] and motivating me to provide
the necessary changes.

As per the current implementation for GB codec driver, a jack list is
maintained for each module. And it expects the list to be populated by
the snd_soc_jack structure which would require modifications in
mainstream code.
However, this is not a necessary requirement and the list can be easily
maintained within gbaudio_module_info as well. This patch provides the
relevant changes for the same.

* [RESEND PATCH v1 2/6] staging: greybus: audio: Maintain jack list within GB Audio module

As per the current implementation for GB codec driver, a jack list is
maintained for each module. And it expects the list to be populated by
the snd_soc_jack structure which would require modifications in
mainstream code.
However, this is not a necessary requirement and the list can be easily
maintained within gbaudio_module_info as well. This patch provides the
relevant changes for the same.

Due to dependencies on ASoC framework changes, GB dummy codec module
compilation is currently disabled. This patch updates codec driver as
per the latest ASoC APIs.

Greybus Codec driver allows modules to be dynamically added and removed,
which further requires updating the DAPM configurations as well.
With current snd_soc architecture, dynamic audio modules is not yet
supported. This patch provides helper APIs to update DAPM configurations
in response to modules which are dynamically added or removed. The
source is primarily based on snd_dapm.c

Greybus Codec driver allows modules to be dynamically added and removed,
which further requires updating the DAPM configurations as well.
With current snd_soc architecture, dynamic audio modules is not yet
supported. This patch provides helper APIs to update DAPM configurations
in response to modules which are dynamically added or removed. The
source is primarily based on snd_dapm.c

Currently, GB codec and audio module is conditionally compiled based on
GREYBUS_AUDIO_MSM8994. However, audio module is not dependent on MSM8994
platform and can be used generically with any platform that follows
GB Audio class specification.
Also, GB codec driver corresponds to dummy codec represented by I2S port
available on Toshiba AP Bridge. Added config option for the same in
kconfig file and accordingly updated Makefile.

Currently, GB codec and audio module is conditionally compiled based on
GREYBUS_AUDIO_MSM8994. However, audio module is not dependent on MSM8994
platform and can be used generically with any platform that follows
GB Audio class specification.
Also, GB codec driver corresponds to dummy codec represented by I2S port
available on Toshiba AP Bridge. Added config option for the same in
kconfig file and accordingly updated Makefile.

This code would be nicer without the "jack" pointer. Just use
"module->headset_jack" directly so that it's easier to use grep on the
code.

Use "sizeof(*button)". It's the same size so it doesn't affect runtime.

Because we got rid of the jack pointer then we can re-use the name here.
struct gbaudio_jack *jack, *n;
We still don't want the "struct snd_soc_jack *jack;" pointer.

Since we renamed "gba_jack" to "jack" then this becomes:
snd_device_free(card->snd_card, jack->jack.jack);
Which is sort of weird, but still okay.

Don't introduce unused assignments. It just silences static checker
warnings about uninitialized variables and introduces bugs.
Anyway, the same comments for the rest of the patch. Please don't
introduce so many variables which aren't required and which hurt
grep-ability.

Because we got rid of the jack pointer then we can re-use the name here.
struct gbaudio_jack *jack, *n;
We still don't want the "struct snd_soc_jack *jack;" pointer.

I quite like the "component" pointer because it's assigned once at the
start of the function and used consistently throughout. The other
pointers I complained about were just temporary pointers which meant
different things depending on which line you were on. They made the
code harder to read.
My only quible is that in the next patch it's called "comp" and here
it's called "component". Let's just use "comp" for all the local
variables.

Please rename "gbcodec" in a different patch. It's not related to
fixing the compile.
Otherwise it seems okay.

Please rename "gbcodec" in a different patch. It's not related to
fixing the compile.
Otherwise it seems okay.

This commit message was a bit confusing to me. Just say:
"Currently you can't enable the Grey Bus Audio Codec because there is no
entry for it in the Kconfig file. Originally the config name was going
to be AUDIO_MSM8994 but that's not correct because other types of
hardware are supported now. I have chosen the name AUDIO_APB_CODEC
instead. Also I had to update the dependencies for GREYBUS_AUDIO to
make the compile work."
Otherwise this looks fine.
