+See Documentation/devicetree/bindings/mfd/madera.txt

+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

-Allwinner Sony/Philips Digital Interface Format (S/PDIF) Controller
-
-The Allwinner S/PDIF audio block is a transceiver that allows the
-processor to receive and transmit digital audio via an coaxial cable or
-a fibre cable.
-For now only playback is supported.
-
-Required properties:
-
- - compatible : should be one of the following:
- - "allwinner,sun4i-a10-spdif": for the Allwinner A10 SoC
- - "allwinner,sun6i-a31-spdif": for the Allwinner A31 SoC
- - "allwinner,sun8i-h3-spdif": for the Allwinner H3 SoC
-
- - reg : Offset and length of the register set for the device.
-
- - interrupts : Contains the spdif interrupt.
-
- - dmas : Generic dma devicetree binding as described in
- Documentation/devicetree/bindings/dma/dma.txt.
-
- - dma-names : Two dmas have to be defined, "tx" and "rx".
-
- - clocks : Contains an entry for each entry in clock-names.
-
- - clock-names : Includes the following entries:
- "apb" clock for the spdif bus.
- "spdif" clock for spdif controller.
-
- - resets : reset specifier for the ahb reset (A31 and newer only)
-
-Example:
-
-spdif: spdif@1c21000 {
- compatible = "allwinner,sun4i-a10-spdif";
- reg = <0x01c21000 0x40>;
- interrupts = <13>;
- clocks = <&apb0_gates 1>, <&spdif_clk>;
- clock-names = "apb", "spdif";
- dmas = <&dma 0 2>, <&dma 0 2>;
- dma-names = "rx", "tx";
-};
