4afdd89df0 ASoC: tas2552: Code, define alignment changes for uniformity
Align the numbers in the header file to the same column.
At the same time change the wrapping of CFG_2 register write in the probe
function to be uniform with the other calls.

2a9dd1db70 ASoC: tas2552: Correct Boost Auto-Pass Through Control register usage
Correct the bit definition so the code will change the bits what it
supposed to change. Also rename the register define to
TAS2552_BOOST_APT_CTRL.

b2822f191a ASoC: tas2552: Correct Output Data register usage
Do not write to DOUT Tristate register at probe time, specially not write
data which is defined to be used in Output Data Register.
Fix the defines for the Output Data Register and correct the register write
at probe time.

1014f7eff9 ASoC: tas2552: Correct the PLL configuration
Do not restrict the sampling rate to 44.1/48KHz. The pll_clk clock should
be (sampling rate * 512) in all cases.
Correct the J.D calculation (the D part was incorrectly calculated).
Restore PLL enable status after we are done with the configuration.
Implement hardware constraint handling towards the pll_clkin:
if D != 0 (in J.D) then 1.1MHz <= pll_clkin <= 9.2MHz needs to be checked.
If the PLL setup does not met with this constraint, fall back to BCLK as
reference clock, if BCLK fails, use the internal 1.8MHz clock.

a571cb17ac ASoC: tas2552: Configure the WCLK frequency based on the stream
Instead of hard wiring the WCLK frequency at probe time do it runtime.
The hard wired 88_96KHz was not even setting the correct bits since it was
defined as (1 << 6) which will  change the I2S_OUT_SEL bit and will leave
the amplifier configured for 8KHz.
At the same time clean up and fix the CFG3 register bits.

d20b098dd9 ASoC: tas2552: Add support for word length configuration
Configure the word length based on the params_width of the stream.
Also configure the clock per frame value which is used when tas2552 is bus
master.

3f747a810e ASoC: tas2552: Add TDM support
TDM support is achieved using DSP transfer mode and setting a programmable
offset which specifies where data begins with respect to the frame sync.

definition in one place and correct the bit shifts at the same time.

89683fdefd ASoC: tas2552: Correct PDM configuration register bit definitions
The PDM clock can be selected via bit0-1.
PDM_DATA_ES bit is at bit2.

The code were trying to select BCLK as PDM reference clock but instead
it was selecting PLL and set the DATA_ES bit to 1.
Selecting the PLL output as reference clock as default does make sense,
but the driver should not change the PDM data edge.

5df7f71d5c ASoC: tas2552: Support TI TAS2552 Amplifier
Support the TI TAS2552 Class D amplifier.

The TAS2552 is a high efficiency Class-D audio
power amplifier with advanced battery current
management and an integrated Class-G boost
The device constantly measures the
current and voltage across the load and provides a
digital stream of this information.
