* mfd: Convert twl6040 to i2c driver, and separate it from twl corePeter Ujfalusi2012-04-161-0/+27
| | | | | | | | | | | | | | 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 noisePeter Ujfalusi2011-10-121-0/+1
| | | | | | | | | | 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. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* MFD: twl6040: function to query the vibra status for clientsPeter Ujfalusi2011-10-121-0/+3
| | | | | | | | | | | | 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 registersPeter Ujfalusi2011-10-121-0/+1
| | | | | | | | | | | 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 definitionsPeter Ujfalusi2011-10-121-13/+7
| | | | | | | | | | | 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.

* ASoC: twl6040: Chip initialization cleanupPeter Ujfalusi2011-09-191-3/+0
| | | | | | | | | | | | | | There is no need to write to the vio registers at probe time, since most them either read only, or shared with MFD or not used. On the other hand it is a good idea to updated the ASICREV register in the cache at this time. After power up we need to restore some registers. Clean up the list to contain only the registers we are going to restore.

* mfd: twl6040: Add initial supportMisael Lopez Cruz2011-07-041-0/+255
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.
