The Marvell PXA SSP block is the same or similiar to the MMP2 variant.
The only difference in the binding is the PXA version supports DMA (and
that's probably a binding difference rather than an actual h/w
difference).
The old binding didn't belong under 'serial' as it is not a UART. The
SSP block also supports audio devices, so 'spi' is not a perfect fit
either. As the existing schema for MMP2 is there, just leave things
as-is.
The examples in the old text binding were pretty out of sync with
reality. 'clock-names' and 'ssp-id' aren't documented nor used.

This corner case has never been supported and it is going to need topology
updates for DMIC copier to support multiple formats.

When constructing packets to DSP, the Audioreach code uses 'struct
audioreach_module_config' to configure parameters like number of
channels, bitrate, sample rate etc, but uses defaults for the channel
mapping.
Rework this code to copy the channel mapping from 'struct
audioreach_module_config', instead of using the default. This requires
all callers to fill that structure: add missing initialization of
channel mapping.
Entire patch makes code more logical and easier to follow:
1. q6apm-dai and q6apm-lpass-dais code which allocates 'struct
audioreach_module_config' initializes it fully, so fills both
the number of channels and the channel mapping.
2. Audioreach code, which uses 'struct audioreach_module_config' when
constructing packets, copies entire contents of passed config, not
only pieces of it.

The set_channel_map() implementation in q6apm-lpass-dais driver was
copying older pre-Audioreach code from q6afe-dai driver, but not really
using it. The code sets active channel mask based on passed channel
mapping, but Audioreach code does not use that mask ever. Audioreach
module configuration does have on the other hand proper channel mapping
field, which should supersed that active channel mask.
Drop the unused active channel mask and implement proper mapping of
channels in q6apm-lpass-dais driver.

There is no need for implementations of DAI set_channel_map() to modify
contents of passed arrays with actual channel mapping. Additionally,
the caller keeps full ownership of the array.
Constify these pointer arguments so the code will be safer and easier to
read (documenting the caller's ownership).

Add support for the Everest-semi ES8311 codec.
Everest-semi ES8311 codec is a low-power mono audio codec with I2S audio
interface and I2C control.
Supported features:
* Both master and slave mode. Master clock is optional in slave mode.
* Sample rates from 8KHz to 96KHz.
* Sample formats: S16_LE, S18_3LE, S20_3LE, S24_3LE, S24_LE and S32_LE.
* I2S formats: I2S, LEFT_J, DSP_A, DSP_B.
* BCLK and FSYNC clocks inversion.
* Component suspend/resume.
* ADC, PGA, DAC controls.
* ADC DSP controls: volume, fade (ramp rate), ALC, automute, HPF, EQ.
* DAC DSP controls: volume, fade (ramp rate), DRC, EQ.
* DAPM routes: capture path with input source selection (differential
MIC/DMIC) and AIF channel source selection; playback path with DAC
channel source selection.
Limitations:
* Support only for master clocks with a ratio of ADC (or DAC) clock to
LRCLK equal to 256. This to keep the default ADC and DAC oversampling
and ADC scale settings. Anyway all 8-96KHz sample rates are supported
when the ratio of MCLK to sample rate is 32, 64, 128, 256, 384 or 512
(upper limit due to max MCLK freq of 49.2MHz).
* Coefficients for ADC HPF and ADC/DAC EQ not supported.
* Digital mic supported but not tested.
* S18_3LE, S20_3LE and S24_3LE formats supported but not tested.
