mfd: Add support for twl6041

2012-07-24T22:27:13+00:00

The delta between twl6040 and twl6041 is small, the main difference is in
the number of GPOs (3 on twl6040, 1 on twl6041).

mfd: Remove unneeded io_mutex from struct twl6040

2012-07-16T13:27:09+00:00

Current code has been converted to use regmap APIs, the io_mutex is not needed.
Thus remove the io_mutex.

mfd: Add regulator support for twl6040 VIO, V2V1 supplies

2012-05-09T19:55:45+00:00

twl6040 has three power supply source:
VBAT needs to be connected to VBAT, VIO, and V2V1.
Add regulator support for the VIO, V2V1 supplies.
Initially handle the two supply together with bulk commands.

mfd: Convert twl6040 to i2c driver, and separate it from twl core

2012-04-16T14:45:34+00:00

Complete the separation of the twl6040 from the twl core since
it is a separate chip, not part of the twl6030 PMIC.

Make the needed Kconfig changes for the depending drivers at the
same time to avoid breaking the kernel build (vibra, ASoC components).

ASoC: twl6040: Workaround for headset DC offset caused pop noise

2011-10-12T12:11:54+00:00

Both Headset DAC need to be turned on/off at the same time before
any of the output drivers are enabled (HS Left/Right, Earpiece).
Move the HS DAC enable code to sequenced DAPM_SUPPLY, and attach
it to the DACs.

MFD: twl6040: function to query the vibra status for clients

2011-10-12T10:48:49+00:00

If the client only interested, if any of the vibra channels enabled, or
if any of the channels are set to receive audio data via PDM.

This function targets mainly the vibra driver, so it can check if it is
allowed to execute effects ot not.

MFD: twl6040: Cache the vibra control registers

2011-10-12T10:48:46+00:00

The vibra control register will be used from the ASoC codec driver as well.
In order to avoid latency issues caused by I2C read access, cache the two
control register within the core driver, so we do not need to reach out
to the chip to read it back.

Input: twl6040: Simplify vibra regsiter definitions

2011-10-12T10:48:35+00:00

The bits within the two control registers (for left and right channel)
are identical.
Use common names for the bits acros the two register.
Also add the missing definition for the path selection bit.
