ASoC: dt-bindings: fsl_asrc: Add new property fsl, asrc-format
In order to support new EASRC and simplify the code structure,
We decide to share the common structure between them. This bring
a problem that EASRC accept format directly from devicetree, but
ASRC accept width from devicetree.

In order to align with new ESARC, we add new property fsl,asrc-format.
The fsl,asrc-format can replace the fsl,asrc-width, then driver
can accept format from devicetree, don't need to convert it to
format through width.

ASoC: dt-bindings: fsl_asrc: add compatible string for imx8qm & imx8qxp
Add compatible string "fsl,imx8qm-asrc" for imx8qm platform,
"fsl,imx8qxp-asrc" for imx8qxp platform.

There are two asrc modules in imx8qm & imx8qxp, the clock mapping is
different for each other, so add new property "fsl,asrc-clk-map"
to distinguish them.

ASoC: fsl: Mark 'big-endian' property as optional
Currently the 'big-endian' property is listed as required, which is
not correct. i.MX SoCs do not need such property, so move it under
'Optional properties' entry instead.

Also, fsl-sai.txt incorrectly referenced 'FTM_PWM registers', so
change it to 'SAI registers', which is the intended description.

48c926cd34 dt-bindings: Remove leading zeros from bindings notation
Improve the binding example by removing all the leading zeros to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have leading 0s

Converted using the following command:

perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"`

Some unnecessary changes were manually fixed.

4da722ca19 dt-bindings: Remove "status" from examples
Pretty much any node can have a status property, so it doesn't need to
be in examples.

Converted with the following command and removed examples with SoC and
board specific splits:

git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d'

13b8a97a76 ASoC: fsl_asrc: spba clock is needed by asrc device
ASRC need to enable the spba clock, when sdma is using share peripheral
script. In this case, there is two spba master port is used, if don't
enable the clock, the spba bus will have arbitration issue, which may
cause read/write wrong data from/to ASRC registers

3117bb3109 ASoC: fsl_asrc: Add ASRC ASoC CPU DAI and platform drivers
The Asynchronous Sample Rate Converter (ASRC) converts the sampling rate of a
signal associated with an input clock into a signal associated with a different
output clock. The driver currently works as a Front End of DPCM with other Back
Ends DAI links such as ESAI<->CS42888 and SSI<->WM8962 and SAI. It converts the
original sample rate to a common rate supported by Back Ends for playback while
converts the common rate of Back Ends to a desired rate for capture. It has 3
pairs to support three different substreams within totally 10 channels.
