sound updates for 5.3 

Many updates in this development cycle are found in ASoC where it got
 a wide range of changes for the continued refactoring.
 Some highlights are below.
 
 ASoC:
 * Continued refactoring work by Morimoto-san toward the full
   componentization; the changes are seen allover the places
 * Support for force disconnecting muxes in DAPM
 * Continued development of ASoC Intel SOF stuff
 * New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90,
   Conexant CX2072X, Realtek RT1011 and RT1308
 
 HD-audio:
 * More fixes and adjustments for ASoC SOF HD-audio
 * Fix for resume problem on some Realtek codecs
 
 USB-audio:
 * A few fixes for the issues reported by syzbot USB fuzzer
 * Fix for UAC2 extension unit parser
 * Quirks for Line6 Helix, Emgaic Unitor 8
 
 FireWire:
 * Lots of code refactoring and fixes in most of its components

Cirrus Logic Madera class audio codecs
This describes audio configuration bindings for these codecs.
See also the core bindings for the parent MFD driver:
See Documentation/devicetree/bindings/mfd/madera.txt
and defines for values used in these bindings:
include/dt-bindings/sound/madera.h
These properties are all contained in the parent MFD node.
Optional properties:
- cirrus,dmic-ref : Indicates how the MICBIAS pins have been externally
connected to DMICs on each input, one cell per input.
<IN1 IN2 IN3 ...>
A value of 0 indicates MICVDD and is the default, other values depend on the
codec:
For CS47L35 one of the CS47L35_DMIC_REF_xxx values
For all other codecs one of the MADERA_DMIC_REF_xxx values
Also see the datasheet for a description of the INn_DMIC_SUP field.
- cirrus,inmode : A list of input mode settings for each input. A maximum of
16 cells, with four cells per input in the order INnAL, INnAR INnBL INnBR.
For non-muxed inputs the first two cells for that input set the mode for
the left and right channel and the second two cells must be 0.
For muxed inputs the first two cells for that input set the mode of the
left and right A inputs and the second two cells set the mode of the left
and right B inputs.
Valid mode values are one of the MADERA_INMODE_xxx. If the array is shorter
than the number of inputs the unspecified inputs default to
MADERA_INMODE_DIFF.
- cirrus,out-mono : Mono bit for each output, maximum of six cells if the
array is shorter outputs will be set to stereo.
- cirrus,max-channels-clocked : Maximum number of channels that I2S clocks
will be generated for. Useful when clock master for systems where the I2S
bus has multiple data lines.
One cell for each AIF, use a value of zero for AIFs that should be handled
normally.
- cirrus,pdm-fmt : PDM speaker data format, must contain 2 cells
(OUT5 and OUT6). See the PDM_SPKn_FMT field in the datasheet for a
description of this value.
The second cell is ignored for codecs that do not have OUT6.
- cirrus,pdm-mute : PDM mute format, must contain 2 cells
(OUT5 and OUT6). See the PDM_SPKn_CTRL_1 register in the datasheet for a
description of this value.
The second cell is ignored for codecs that do not have OUT6.
Example:
cs47l35@0 {
compatible = "cirrus,cs47l35";
cirrus,dmic-ref = <0 0 CS47L35_DMIC_REF_MICBIAS1B 0>;
cirrus,inmode = <

MADERA_INMODE_SE MADERA_INMODE_SE /* IN1B single-ended */
MADERA_INMODE_DIFF MADERA_INMODE_DIFF /* IN2 differential */
