This series contains a bunch of fairly minor changes which overhaul and
modernise the WM8731 driver, there should be no impact on the driver's
functionality.
The AT91SAM9G20-EK audio driver is replacing any error code returned by
atmel_ssc_set_audio() with -EINVAL which could be unhelpful for debugging.
Pass through the error code, and include it in the log message we print for
good measure.

The error handling in the AT91SAM9G20-EK machine driver probe did not
consistently free the SSC in error paths, sometimes immediately returning
an error rather than doing cleanup. Fix this.

The MCLK of the WM8731 on the AT91SAM9G20-EK board is connected to the
PCK0 output of the SoC, intended in the reference software to be supplied
using PLLB and programmed to 12MHz. As originally written for use with a
board file the audio driver was responsible for configuring the entire tree
but in the conversion to the common clock framework the registration of
the named pck0 and pllb clocks was removed so the driver has failed to
instantiate ever since.
Since the WM8731 driver has had support for managing a MCLK provided via
the common clock framework for some time we can simply drop all the clock
management code from the machine driver other than configuration of the
sysclk rate, the CODEC driver still respects that configuration from the
machine driver.

Placing both the I2C and SPI code in the same module causes problems with
mixes of modular and non-modular builds of the buses so it's generally bad
practice. As with other drivers split the bus code out of the WM8731 driver
into separate modules.

In function mchp_pdmc_af_put(), Intel's kernel test robot reports the
following warning:
sound/soc/atmel/mchp-pdmc.c:186:34: warning: address of array \
'uvalue->value.integer.value' will always evaluate to 'true' \
[-Wpointer-bool-conversion]
This is because we are using `uvalue->value.integer.value` which its
type is `long value[128];` for conditional expression and that array
will always decay to a non-NULL pointer. Using a non-NULL pointer for
conditional expression will always evaluate to true.
Fix this by changing it to `uvalue->value.integer.value[0]` as that's
what the mchp_pdmc_af_get() function sets.

Merge series from Codrin Ciubotariu <codrin.ciubotariu@microchip.com>:
This patch series adds support for Pulse Density Microphone Controller
(PDMC), present on Microchip's SAMA7G5.
The PDMC interfaces up to 4 digital microphones having Pulse Density
Modulated (PDM) outputs. It generates a single clock line and samples 1 or
2 data lines. The signal path includes an audio grade programmable
decimation filter and outputs 24-bit audio words.
The source of each channel can be independently defined as PDMC_DS0 or
PDMC_DS1, sampled at the rising or falling edge of PDMC_CLK.
The patch series starts with a fix on the ASoC DMA engine support. Then
continues with the bindings and the driver of PDMC. It is followed by the
DT nodes for SAMA7G5 and SAMA7G5-EK. In the end, the drivers for PDMC
and PDM microphones are enabled in sama7_defconfig.

SAMA7G5's I2S-MCC has 4 pairs of DIN/DOUT pins. Since TDM only uses a
single pair of pins for synchronous capture and playback, the controller
needs to be told which of the pair is connected. This can be mentioned
using the "microchip,tdm-data-pair" property from DT. The property is
optional, useful only if TDM is used. If it's missing, DIN/DOUT 0 pins
will be used by default.

Instead of manually managing its DMA buffers using
dma_{alloc,free}_coherent() lets the sound core take care of this using
managed buffers.
On one hand this reduces the amount of boiler plate code, but the main
motivation for the change is to use the shared code where possible. This
makes it easier to argue about correctness and that the code does not
contain subtle bugs like data leakage or similar.
