      1NXP MICFIL Digital Audio Interface (MICFIL).
      2
      3The MICFIL digital interface provides a 16-bit audio signal from a PDM
      4microphone bitstream in a configurable output sampling rate.
      5
      6Required properties:
      7
      8  - compatible		: Compatible list, contains "fsl,imx8mm-micfil"
      9			  or "fsl,imx8mp-micfil"
     10
     11  - reg			: Offset and length of the register set for the device.
     12
     13  - interrupts		: Contains the micfil interrupts.
     14
     15  - clocks		: Must contain an entry for each entry in clock-names.
     16
     17  - clock-names		: Must include the "ipg_clk" for register access and
     18			  "ipg_clk_app" for internal micfil clock.
     19
     20  - dmas		: Generic dma devicetree binding as described in
     21			  Documentation/devicetree/bindings/dma/dma.txt.
     22
     23Example:
     24micfil: micfil@30080000 {
     25	compatible = "fsl,imx8mm-micfil";
     26	reg = <0x0 0x30080000 0x0 0x10000>;
     27	interrupts = <GIC_SPI 109 IRQ_TYPE_LEVEL_HIGH>,
     28		     <GIC_SPI 110 IRQ_TYPE_LEVEL_HIGH>;
     29	clocks = <&clk IMX8MM_CLK_PDM_IPG>,
     30		 <&clk IMX8MM_CLK_PDM_ROOT>;
     31	clock-names = "ipg_clk", "ipg_clk_app";
     32	dmas = <&sdma2 24 26 0x80000000>;
     33};
