[PATCH v3 0/9] OMAP4: ASoC: Support for PandaBoard family

[PATCH v3 0/9] OMAP4: ASoC: Support for PandaBoard family

[Peter Ujfalusi]

Hello,

the following series will add ASoC support for PandaBoards.
PandaBoards have different audio routings compared to SDP4430/Blaze boards, but
the differences not that big to justify a new ASoC machine driver.

This series is based on the first three patch from the v1 sereis (those, which
has been applied by Liam).

Changes since v2:
- Remove direct board dependency for the ASoC machine driver (replaced by
  ARCH_OMAP4)
- mach-omap2/board-omap4panda: Generic board revision handling function instead
  of dedicated for audio.
- Macro twl6040_disconnect_pin replaced with a function

Changes since v1:
As suggested by Mark the platform data, machine driver has been converted to
process feature flags instead of Board IDs.
- The ASoC machine driver registers all DAPM widgets. Based on the received
  configuration it will disable the unused paths
- PCM for dmic is only created, if the board has digital mic conencted
- Jack functionality will be only used on boards supporting it
- Sound card name for SDP4430 has net been changed

Regards,
Peter

I have to say I'm still really unhappy with the name - it's not like we
should ever be seeing an omap-twl6040 driver but the naming suggests
that there should be.  Bypassing the ABE ought to be a runtime decision
as it's policy and might change with use case.  But anyway:

[PATCH v3 3/9] ASoC: omap-abe-twl6040: Convert to platform deriver

[Peter Ujfalusi]

Convert the OMAP4 ABE/TWL6040 machine driver to platform
driver.
For the card name use the string provided via platform data.
The card's name for OMAP4 SDP4430 has been changed:
SDP4430 -> OMAP4-SDP4430

[PATCH v3 6/9] ASoC: omap-abe-twl6040: DAI link selection based on platform data

[Peter Ujfalusi]

We can have machines without DMIC connected. In this case there is
no need to create amother (unusable) capture PCM on the card.
The existence of the DMIC connection can be checked via
pdata->has_dmic.
Select the correct dai_link structure for the card based on
pdata->has_dmic.

[PATCH v3 7/9] ASoC: omap-abe-twl6040: Configure card according to platform data

[Peter Ujfalusi]

Disable the not connected pins on the board based on the
received platform data.
DO not register the jack function on boards, which does not have
means to detect it (jack is always connected).

[PATCH v3 8/9] OMAP4: omap4panda: Enable audio support

[Peter Ujfalusi]

PandaBoard has twl6040 codec for audio.
Register the omap4-abe-twl6040 platform device.
Add platform data to enable the twl6040 codec.
Since there is a difference in audio between  PandaBoard 4430
and PandaBoard ES (4460):
Use different name for the sound card:
"OMAP4-Panda" for PandaBoard 4430
"OMAP4-PandaES" for PandaBoard ES
