Factors out some boilerplate code for drivers doing the default thing
for platform driver registration. Drivers using platform_driver_probe
or an initcall other than module_init can't be converted.Signed-off-by: Mark Brown

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.Signed-off-by: Peter Ujfalusi

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.Signed-off-by: Peter Ujfalusi

Avoid requesting the audpwron gpio in case of ES1.0
revision.
In the past we requested the gpio, but we did not
free it up, since we made the check for the revision
later. This results later checks for gpio validity to
fail, leaving the gpio reserved (even after the driver
has been removed).Signed-off-by: Peter Ujfalusi

There is no need to keep global pointer for the platform
device, since it is only used for dev_* prints, and the
device pointer available within the twl6040 structure.Signed-off-by: Peter Ujfalusi

There is no need to have two different types for
tracking the selected PLL.
Use only the defines, when dealing with the PLLs.Signed-off-by: Peter Ujfalusi

Remove the twl6040_request_irq/free_irq inline functions,
and use direct calls instead in the core driver to
register the threaded irq.Signed-off-by: Peter Ujfalusi

In order to operate correctly twl6040 needs correct
interrupt configuration.
The slave drivers (vibra, and ASoC codec) will refuse
to probe, if the interrupt configuration is not correct.
In this way some checks can be removed from the code.Signed-off-by: Peter Ujfalusi

Provide the irq number for slaves via resource on the
platform device.
The irq number configuration is done in the twl6040-core
at probe time, so machine drivers do not need to be
modified.Signed-off-by: Peter Ujfalusi

Pass twl4030_codec_data instead of the twl4030_audio_data
for the ASoC codec driver.Signed-off-by: Peter Ujfalusi
Acked-by: Samuel Ortiz -
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.
