Subject: [PATCH v2 00/14] MFD/ASoC/Input: twl4030-audio submodule DT support

Hello,

Changes since v1:
- Get the MCLK frequencey from twl-core driver (via new API)
- hs_extmute_disable_level parameter has been removed
- empty of_find_node_by_name() in of.h for !CONFIG_OF builds

Mark: the extmute GPIO handling (when it is used) remained in the codec driver
for now. I can think more on how to add support for this type of mute control.
If you can point me to other codec needing this it would help on designing
something which is common enough for other users.
As for now I have a separate series to add GPIO controlled output amps (hp/spk).
I will send that to review soon.

Introl mail from v1:

The following series adds DT support for the twl4030 audio submodule which
provides audio codec and vibra functionality.

The MFD core driver is probed via DT, it will create the needed child devices
based on the provided information in the DT blob.
Child drivers (vibra, ASoC codec) will parse the core's node if needed to get
the needed parameters for their configuration.

In the ASoC codec driver the hs_extmute callback (which was used to toggle a
GPIO line) has been removed. The codec driver will receive the GPIO number
(if it is needed on the platform).

If the series is OK (and no objections from the maintainers), it would be good
if this can go via audio. Changed files are well contained within the
twl4030-audio stack so I do not expect merge issues later.

The series has been tested on BeagleBoard (with the McBSP DT series, and with
the upcoming DT audio support for BeagleBoard).

Regards,
Peter
