1 NXP MICFIL Digital Audio Interface (MICFIL).
3 The MICFIL digital interface provides a 16-bit audio signal from a PDM
4 microphone bitstream in a configurable output sampling rate.
8 - compatible : Compatible list, contains "fsl,imx8mm-micfil"
11 - reg : Offset and length of the register set for the device.
13 - interrupts : Contains the micfil interrupts.
15 - clocks : Must contain an entry for each entry in clock-names.
17 - clock-names : Must include the "ipg_clk" for register access and
18 "ipg_clk_app" for internal micfil clock.
20 - dmas : Generic dma devicetree binding as described in
21 Documentation/devicetree/bindings/dma/dma.txt.
