ASoC: tlv320aic32x4: Use snd_soc_update_bits() in aic32x4_hw_params()
Make the code easier to read by using snd_soc_update_bits() over
read/modify/write sequences. Also use separate per-register
variables instead of re-using "data". This can prevent accidental
over-writing and makes it clear for which register each bit value is
intended.

ASoC: tlv320aic32x4: Use BIT and GENMASK for bit field definitions
Inter-register definitions should use BIT and GENMASK definitions
and also be grouped by what register they belong to. This makes it
easy to cross-check with the datasheet and is consistent with other
drivers.

ASoC: tlv320aic32x4: Drop define mapping from number to number
Drop definition of frequencies that only map from one number to
the same number. This is not needed and if misused can hide
bugs.

ASoC: tlv320aic32x4: Use AIC32X4_REG macro for all register definitions
All register definitions should use the AIC32X4_REG macro, even the ones
in page 0. This makes datasheet lookup more consistent and helps with
alignment both in this file and across other tlv320aic* drivers.

b9045b9c6b ASoC: tlv320aic32x4: Add gpio configuration to the codec
Add the ability to configure the MFP1->MFP5 registers
as GPIOs.  In addition adding ALSA controls to get and set
the GPIO state.

Per the data sheet each MFP can be configured as a GPIO
input only, output only or either an input or output.

3bcfd222f6 ASoC: tlv320aic32x4: Break out I2C support into separate module
To prepare for abstracting adding SPI support, the I2C pieces needs to
be in its own moudle.  This patch moves common probe code into aic32x4_probe
and common removal code into aic32x4_remove.  It also creates a static
regmap config structure to be copied in the I2C specific driver.

609e6025b8 ASoC: tlv320aic32x4: Fix MICPGA input configuration
Currently the Negative Terminal Input Routing Configuration is only set
when there is a special routing configuration. If we don't use one of
the inputs IN1 or IN2 as negative terminal input, the PGA and recording
does not work.

This patch adds a route from CM1L/CM1R to the PGA as negative input by
default. With this configuration the PGA can amplify all input signals
and line-in/mic works again.

b44aa40f87 ASoC: tlv320aic32x4: Fix mono playback
Playback of a mono stream should output the same stream on both
channels. At the moment only the left analog signal is valid, the right
one is just noise.

This patch maps the left digital channel onto both DACs when receiving a
mono stream.

a405387c68 ASoC: tlv320aic32x4: Fix problem with first capture.
In its previous status, the first capture didn't work properly;
nothing was actually recorded from the microphone. This
behaviour was observed using a Visstrim M10 board.

In order to solve this BUG a workaround has been added that,
during the initialization process of the codec, powers on and
off the ADC.

The issue seems related to a HW BUG or some behavior that
is not documented in the datasheet.

1d471cd126 ASoC: Add TI tlv320aic32x4 codec support.
This patch adds support for tlv320aic3205 and tlv320aic3254 codecs.
It doesn't include miniDSP support for aic3254.
