[PATCH v3 0/5] ASoC/MFD/Input: twl6040: Support for audio driven vibra

[Peter Ujfalusi]

Hello,

Changes since v2:
- Rebased on git://opensource.wolfsonmicro.com/linux-2.6-asoc, for-3.2 branch
- Acked-by lines added to patches.

Intro mail form v1:
The following series adds support for the soc driver to route audio (PCM
stream) to the vibra ports of the twl6040.
We have ALSA controls for the vibra source selection (PDM, or Input/FF).
The route can not be changed from Input/FF to PDM during ongoing effect coming
from Input/FF.
The Input/FF driver can not execute new effect, while the vibra source is
configured to be PDM.
TO get things working in legacy mode the omap-mcpdm, and twl6040 soc codec
driver's channel count needed to be fixed.

To minimize the need for reads through the I2C bus, the MFD driver will cache
the vibra control registers.

With this series we can route PCM audio to drive the twl6040 vibra output.
In order to that we need to play 5 channel audio, and place the vibra sample at
the 5th channel. This will change with ABE support (change == simplified).

The series has been created on top of:
git://opensource.wolfsonmicro.com/linux-2.6-asoc, for-3.2 branch

If there are no objections, it would be good if this series goes via audio.

Regards,
Peter
