Peter Ujfalusi 8eaeb93933 mfd: Convert twl6040 to i2c driver, and separate it from twl core
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).

Takashi Iwai 650d6e25cd This has been a very active release for ASoC, as well as the usual raft
of bugfixes and driver updates there's quite a few framework enhancements.
 Most are either small or are laying the groundwork for user visible
 features (especially dynamic PCM), the most directly visible change is
 the dmaengine library.  There's also a bunch of regmap API enhancements
 pulled into the tree so that either the framework or drivers can take
 advantage of the new features.
 
 Changes include:
 
 - Support for widgets not associated with a CODEC, an important part of
   the dynamic PCM framework.
 
 - A library factoring out the common code shared by dmaengine based DMA
   drivers contributed by Lars-Peter Clausen.  This will save a lot of
   code and make it much easier to deploy enhancements to dmaengine.
 
 - Support for binary controls, used for providing runtime configuration
   of algorithm coefficients.
 
 - A new DAPM widget type for regulator supplies allowing drivers for
   devices that can power down unused supplies while active to do without
   any per-driver code.
 
 - DAPM widgets for DAIs, initially giving a speed boost for playback
   startup and shutdown and also the basis for CODEC<->CODEC DAI link
   support.
 
 - Support for specifying the number of significant bits on audio
   interfaces, useful for allowing applications to know how much effort to
   put into generating data for a larger sample format.
 
 - Conversion of the FSI driver used on some SH processors to DMAEngine.
 
 - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics WM2200.

Lars-Peter Clausen 85e7652d89 ASoC: Constify snd_soc_dai_ops structs
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure")
introduced the possibility to have constant DAI ops structures, yet this is
barley used in both existing drivers and also new drivers being submitted,
although none of them modifies its DAI ops structure. The later is not
surprising since existing drivers are often used as templates for new drivers.
So this patch just constifies all existing snd_soc_dai_ops structs to eliminate
the issue altogether.

The patch was generated with the following coccinelle semantic patch:
// <smpl>
@@
identifier ops;
@@
-struct snd_soc_dai_ops ops =
+const struct snd_soc_dai_ops ops =
{ ... };
// </smpl>

Peter Ujfalusi 35dec69757 ASoC: twl6040: Request core to inline the DAPM sequence
We need to have as less time between McPDM shutdown,
and power down of the DAC on the twl6040 codec as possible.
Request core to ignore the pmdown_time for the playback
stream.
Backround: with the McPDM protocol we are sendning not only
the pure audio stream, but OMAP McPDM also transmits
additional information (for example offset cancellation).
If McPDM is stopped prior to the DAC this information will
be not sent to the codec, which can result noise rendered
by the twl6040 codec.

Peter Ujfalusi 4548dc3c05 ASoC: twl6040: Fix comments for register names
Change the register name strings in the comments for the
twl6040_reg table, so it is easier to search for specific
register.

This is cosmetic change.

Before we had for example:
TWL6040_REG_HSLCTL as register definition.

At the register table we had:
TWL6040_HSLCTL

Searching for TWL6040_HSLCTL resulted no hits.

While if we look for REG_HSLCTL, we can find the places
the register has been used.

Peter Ujfalusi 3acef6854c ASoC: twl6040: Lower the power on gain values at startup
The default gains on outputs/inputs are set to 0dB.
This is fixing the pop noise issue at the first playback, which
caused by the wrong starting point of the ramp code.
The ramp code for the outputs expects the gains to be in
their lowest configuration in order to be effective.
After the playback stops, the ramp code takes care of
ramping down the gains to their minimum.

Reset the twl6040_reg array to hold the chip default values.
The only changed values were for the microphone input selection.
Select no input for the microphones in the twl6040_init_chip function.

Peter Ujfalusi a52762eee9 ASoC: twl6040: Chip initialization cleanup
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.
