-NXP Audio Mixer (AUDMIX).
-
-The Audio Mixer is a on-chip functional module that allows mixing of two
-audio streams into a single audio stream. Audio Mixer has two input serial
-audio interfaces. These are driven by two Synchronous Audio interface
-modules (SAI). Each input serial interface carries 8 audio channels in its
-frame in TDM manner. Mixer mixes audio samples of corresponding channels
-from two interfaces into a single sample. Before mixing, audio samples of
-two inputs can be attenuated based on configuration. The output of the
-Audio Mixer is also a serial audio interface. Like input interfaces it has
-the same TDM frame format. This output is used to drive the serial DAC TDM
-interface of audio codec and also sent to the external pins along with the
-receive path of normal audio SAI module for readback by the CPU.
-
-The output of Audio Mixer can be selected from any of the three streams
- - serial audio input 1
- - serial audio input 2
- - mixed audio
-
-Mixing operation is independent of audio sample rate but the two audio
-input streams must have same audio sample rate with same number of channels
-in TDM frame to be eligible for mixing.

-Device driver required properties:
-=================================
-  - compatible		: Compatible list, contains "fsl,imx8qm-audmix"
-
-  - reg			: Offset and length of the register set for the device.
-
-  - clocks		: Must contain an entry for each entry in clock-names.
-
-  - clock-names		: Must include the "ipg" for register access.
-
-  - power-domains	: Must contain the phandle to AUDMIX power domain node
-
-  - dais		: Must contain a list of phandles to AUDMIX connected
-			  DAIs. The current implementation requires two phandles
-			  to SAI interfaces to be provided, the first SAI in the
-			  list being used to route the AUDMIX output.
-
-Device driver configuration example:
-======================================
-  audmix: audmix@59840000 {
-    compatible = "fsl,imx8qm-audmix";
-    reg = <0x0 0x59840000 0x0 0x10000>;
-    clocks = <&clk IMX8QXP_AUD_AUDMIX_IPG>;
-    clock-names = "ipg";
-    power-domains = <&pd_audmix>;
-    dais = <&sai4>, <&sai5>;
-  };
