Merge tag 'asoc-v5.11' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Updates for v5.11

There's a lot of changes here but mostly cleanups and driver specific
things, the most user visible change is the support for boot time
selection of Intel DSP firmware which will make it easier for people to
move over to the preferred modern implementations in distros and other
large scale deployments.

This also includes a merge of the new auxillary bus which was done in
anticipation of use by the Intel DSP drivers which didn't quite make it.

 - Lots more cleanups and simplifications from Morimoto-san.
 - Support for some basic DPCM systems in the audio graph card from
   Sameer Pujar.
 - Remove some old pre-DT Freescale drivers for platforms that are now
   DT only.
 - Move selection of which Intel DSP implementation to use to boot time
   rather than requiring it to be selected at build time.
 - Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel
   Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek RT715,
   Qualcomm SM8250 and simple GPIO based muxes.

-STMicroelectronics STM32 Serial Audio Interface (SAI).
-
-The SAI interface (Serial Audio Interface) offers a wide set of audio protocols
-as I2S standards, LSB or MSB-justified, PCM/DSP, TDM, and AC'97.
-The SAI contains two independent audio sub-blocks. Each sub-block has
-its own clock generator and I/O lines controller.
-
-Required properties:
-  - compatible: Should be "st,stm32f4-sai" or "st,stm32h7-sai"
-  - reg: Base address and size of SAI common register set.
-  - clocks: Must contain phandle and clock specifier pairs for each entry
-	in clock-names.
-  - clock-names: Must contain "pclk" "x8k" and "x11k"
-	"pclk": Clock which feeds the peripheral bus interface.
-	        Mandatory for "st,stm32h7-sai" compatible.
-	        Not used for "st,stm32f4-sai" compatible.
-	"x8k": SAI parent clock for sampling rates multiple of 8kHz.
-	"x11k": SAI parent clock for sampling rates multiple of 11.025kHz.
-  - interrupts: cpu DAI interrupt line shared by SAI sub-blocks
-
-Optional properties:
-  - resets: Reference to a reset controller asserting the SAI
-
-SAI subnodes:
-Two subnodes corresponding to SAI sub-block instances A et B can be defined.
-Subnode can be omitted for unsused sub-block.
-
-SAI subnodes required properties:
-  - compatible: Should be "st,stm32-sai-sub-a" or "st,stm32-sai-sub-b"
-	for SAI sub-block A or B respectively.
-  - reg: Base address and size of SAI sub-block register set.
-  - clocks: Must contain one phandle and clock specifier pair
-	for sai_ck which feeds the internal clock generator.
-	If the SAI shares a master clock, with another SAI set as MCLK
-	clock provider, SAI provider phandle must be specified here.
-  - clock-names: Must contain "sai_ck".
-	Must also contain "MCLK", if SAI shares a master clock,
-	with a SAI set as MCLK clock provider.
-  - dmas: see Documentation/devicetree/bindings/dma/st,stm32-dma.yaml
-  - dma-names: identifier string for each DMA request line
-	"tx": if sai sub-block is configured as playback DAI
-	"rx": if sai sub-block is configured as capture DAI
-  - pinctrl-names: should contain only value "default"
-  - pinctrl-0: see Documentation/devicetree/bindings/pinctrl/st,stm32-pinctrl.yaml
-
-SAI subnodes Optional properties:
-  - st,sync: specify synchronization mode.
-	By default SAI sub-block is in asynchronous mode.
-	This property sets SAI sub-block as slave of another SAI sub-block.
-	Must contain the phandle and index of the sai sub-block providing
-	the synchronization.
-  - st,iec60958: support S/PDIF IEC6958 protocol for playback
-	IEC60958 protocol is not available for capture.
-	By default, custom protocol is assumed, meaning that protocol is
-	configured according to protocol defined in related DAI link node,
-	such as i2s, left justified, right justified, dsp and pdm protocols.
-	Note: ac97 protocol is not supported by SAI driver
-   - #clock-cells: should be 0. This property must be present if the SAI device
-	is a master clock provider, according to clocks bindings, described in
-	Documentation/devicetree/bindings/clock/clock-bindings.txt.
-
-The device node should contain one 'port' child node with one child 'endpoint'
-node, according to the bindings defined in Documentation/devicetree/bindings/
-graph.txt.

-sound_card {
