Hello,
Changes from the first series:
- twl4030-codec MFD driver is using the mfd-core API (and selects MFD_CORE)
- Added Acked-by: Tony Lindgren <tony@atomide.com> to the patch for the OMAP
board files
- User selectable Kconfig is removed for the TWL4030_CODEC
- soc codec driver patch separated:
- Change the header file, and use the include/linux/mfd/twl4030-codec.h for
register definitions
- The actual change in the soc codec driver
- Module alias corrected in soc codec driver
- The bias is brought up when the driver comes up, rather than in soc probe.
- The soc codec driver is selecting the TWL4030_CODEC driver
The series applies on top of sound-2.6:topic/asoc branch
Commit message from the first series:
The following series adds new MFD device on top of the twl4030 MFD device for
the codec part of the chip, and also converts the soc audio driver to use the
correct probing (device model).
Reason for the twl4030_codec MFD: the vibra control is actually in the codec
part of the twl4030. If both the vibra and the audio functionality is needed
from the twl4030 at the same time, than they need to control the codec power
and APLL at the same time without breaking the other driver.
Also these two has to be able to work without the need for the other driver.
The proposed solution:
Register twl4030_codec as a child for the twl4030 mfd.
twl4030_codec is also and mfd and at the moment it has two child:
twl4030_codec_audio: for audio codec
twl4030_codec_vibra: for vibra driver
The twl4030_codec mfd registers the devices for audio and vibra (if the
platform data is not NULL for them), and has - at the moment - functions to
enable/disable resources, each of these resources has ref-counts, so the
twl4030_codec knows, when the resource is need to be turned on or off.
The interface is quite simple:
int twl4030_codec_enable_resource(enum twl4030_codec_res id);
int twl4030_codec_disable_resource(enum twl4030_codec_res id);
These functions are returning the content of the given register after the
modification (or negative value, if error - the error handling need to be
revisited in a near future), so that the caller can update it's local cache if
it need to do (the audio driver needs it).
There are two resource defined:
TWL4030_CODEC_RES_POWER: Controlling the power of the codec
TWL4030_CODEC_RES_APLL: For APLL
The vibra driver is not part of this series.
I have also included a patch, which changes the board files for those, which
in my knowledge uses the twl4030 codec as audio device. I might missed some
boards...
To-Do list:
- add the actual vibra driver ;)
- coexistence related fixes for the audio and vibra driver
- move all audio related configuration from soc machine drivers to the board
files (if any)

New MFD child to twl4030 MFD device.
Reason for the twl4030_codec MFD: the vibra control is actually in the codec
part of the twl4030. If both the vibra and the audio functionality is needed
from the twl4030 at the same time, than they need to control the codec power
and APLL at the same time without breaking the other driver.
Also these two has to be able to work without the need for the other driver.
This MFD device will be used by the drivers, which needs resources
from the twl4030 codec like audio and vibra.
The platform specific configuration data is passed along to the
child drivers (audio, vibra).

Remove the register descriptions from the twl4030.h file and use
the linux/mfd/twl4030-codec.h instead, which has the codec
related register descriptions also.

To: alsa-devel, linux-omap, sameo; +Cc: linux-kernel, tony, broonie
Change the way how the twl4030 soc codec driver is
loaded/probed.
Use the device probing via tlw4030_codec MFD device.

due to Kconfig ignoring dependencies all the individual machine drivers
are going to need to select this, and SND_SOC_ALL_CODECS will need to
select it if the MFD core is enabled. I should be able to fix this up
myself so no need to repost for that alone.

Hmm, what do you mean by that?
I have checked it, and selecting the machine driver will enables the MFD_CORE
and TWL4030_CODEC in .config, also disabling the machine driver will also
disable the MFD_CORE and the TWL4030_CODEC.
Can you go into details?

Kconfig has never guaranteed to pay any attention to dependencies of
things that were enabled as a result of a select statement - they would
be silently ignored. I've done some tests and it does seem that this is
doing what would be expected at the minute but looking at the Kconfig
changelogs I can't see anything that makes this an intentional change.

As agreed, Mark is taking this one. So:

Applied all, if there's a merge problem with the MFD code then there's a
twl4030-mfd branch at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git
which I'm happy for you to merge if it makes life easier. Due to other
changes the patches end up depending on (just textually I think) there's
a big raft of other stuff in there too, sadly.
