Hello,
The series will do three major things, and they are in one series, because they
pretty much depending on each other, so it is easier to handle them together.
1. Rename the twl4030-codec MFD driver to twl4030-audio
Since the ASoC multicomponent introduction (2.6.37) the twl4030-codec MFD dirver
had been using twl4030-audio to register (twl4030-codec is the ASoC codec
driver). The documentation refers to this part of twl as audio block, so it is
better to rename the driver as well to avoid confusion.
2. Introduction of MFD driver for twl6040.
The TWL6040 audio IC has codec and vibra functionality.
Convert the existing ASoC codec driver to use the new MFD driver's interface.
3. Vibrator driver for TWL6040 (Input/ForceFeedback driver)
The driver itself, and support for the vibrators in SDP4430 board.
The series has been tested on top of merged omap-next, asoc-next, and mfd-next.
It applies on top of linux-next as well.
Regards,
Peter

1.7.5.3
In preparation of renaming the driver from twl4030-codec
to twl4030-audio, first do some clean ups in the driver,
which does not cause any problems outside.

Allign the platform data names for twl4030 audio submodule:
twl4030_audio_data: for the core MFD driver
twl4030_codec_data: for ASoC codec driver
twl4030_vibra_data: for the input/ForceFeedback driver
To avoid breakage, change all depending drivers, files
to use the new types.

From: Misael Lopez Cruz <[email protected]>
TWL6040 IC provides analog high-end audio codec functions for
handset applications. It contains several audio analog inputs
and outputs as well as vibrator support. It's connected to the
host processor via PDM interface for audio data communication.
The audio modules are controlled by internal registers that
can be accessed by I2C and PDM interface.
TWL6040 MFD will be registered as a child of TWL-CORE, and will
have two children of its own: twl6040-codec and twl6040-vibra.
This driver is based on TWL4030 and WM8350 MFD drivers.

From: Misael Lopez Cruz <[email protected]>
Convert TWL6040 CODEC driver into a TWL6040 MFD child, it implies
that MFD-level operations like register accesses, clock setting
and power management are done through MFD APIs, not directly by
CODEC driver anymore. To avoid conflicts with the other MFD child,
vibrator registers are skipped in CODEC driver.

Can you please take a look at creating arch/arm/mach-omap2/i2c-twl.c or
something in common-board-devices.c to get rid of the cut and paste
duplication in every board-*.c file?
Maybe you could have a generic twl_init function that allows overriding
things like keypad with board specific configuration?

Tony

Yes, it would make sense, since most of the board has similar configuration,
and we have lots of duplicated code around.

We might need also support for overriding other configurations
(audio/codec/vibra for sure needs that).
I'll take a look, but I think it is not going to be part of v2 of this series.

Yeah, most of it might be possible to describe with just a flags
like TWL_HAS_VIBRA etc.

We should not do renaming before the clean-up though, it gets
classified as "unnecesary churn".

Or TWL_BOARD_HAS_VIBRA, TWL_BOARD_HAS_CODEC...
For the audio part it is a bit complicated than that:
different base frequencies, for twl6040 we have parameters for Vibra (twl4030
class only have the coexistence). The soc codec has a list of misc parameters
for board specific configurations as well (not all board using them).
I was thinking to switch the MFD driver(s) to use flags to specify the needed
child, and change the child drivers to deal with the missing platform data
themselves.
In that way, board files can pass the vibra/codec platform data to the new
i2c_twl file for example, and provide flags to enable functionality.

The changes in board files are minimal. The biggest part is the code move, and
that will remain the same now or later...

But you could easily remove all the board specific struct twl4030_codec_data
and struct twl4030_codec_audio_data entries by adding a default audio
init option to omap_pmic_init for the common configuration.
How about something like:
void omap_pmic_init(int bus, u32 clkrate, const char *pmic_type, int pmic_irq,
struct twl4030_platform_data *pmic_data, u32 flags);
Where flags would be TWL_BOARD_HAS_DEFAULT_CODEC etc, and if the entry in
pmic_data is NULL, just use the default configuration. I think you already
have the clkrate there?

Can this dependency on twl_i2c_[read/write] be removed,
Since TWL6040 is a separate IC which can get its own i2c_client in
twl6040-core.c and
create its own mfd devices like vibra, audio-codec ... while creating
twl6040-core.c

Yeah, I can grep in the board files, and see what is the most common

common-board-devices.c has omap_pmic_init, but without the flags.

I'll take a look, should we have new file specifically for twl, or should I
extend the common-board-devices.c with the twl related things? IMHO a new file
might be better, since the full twl config might be quite big.

Yeah if it gets big then a separate file is better. Also, if we have
a common init function for twl, then it's easy to add the board specific
device tree initialization to that too and just leave out the calls to
omap_pmic_init from board-*.c files.

Tony

I have parsed the board files for a pattern.
There are some, but I have my doubts as well:
We have eight platform data members in twl4030_platform_data for child
devices.
USB, and audio/codec configuration might worth to move out (since most of the
board does not have fine tuned parameters for codec).
The majority of the code related to pmic is coming from regulator setups, I
can see similarities, but there are differences here and there, which makes
the common configuration mostly useless (different peripherals, boot loader
diffs, etc).
Having said that, I try to create a wrapper for omap_pmic_init, which can
replace the current omap2/3/4_pmic_init, with that we can use common config
for USB, audio, and some selected few regulators initially.
Later other parts might be possible to consolidate as well.
I'm going to call this new wrapper for now omap2/3/4_pmic_config.
Is this a good way to approach this issue?

You are right, twl6040 is separate IC.
I'll take a look how it can be separated from the twl-core (twl6030).
Thanks for noticing this,

Yeah we still need the board specific data passed for sure.
