-NXP MICFIL Digital Audio Interface (MICFIL).
-
-The MICFIL digital interface provides a 16-bit audio signal from a PDM
-microphone bitstream in a configurable output sampling rate.
-
-Required properties:
-
- - compatible : Compatible list, contains "fsl,imx8mm-micfil"
- or "fsl,imx8mp-micfil"
-
- - reg : Offset and length of the register set for the device.
-
- - interrupts : Contains the micfil interrupts.
-
- - clocks : Must contain an entry for each entry in clock-names.
-
- - clock-names : Must include the "ipg_clk" for register access and
- "ipg_clk_app" for internal micfil clock.
-
- - dmas : Generic dma devicetree binding as described in
- Documentation/devicetree/bindings/dma/dma.txt.
-
-Example:
-micfil: micfil@30080000 {
- compatible = "fsl,imx8mm-micfil";
- reg = <0x0 0x30080000 0x0 0x10000>;
- interrupts = <GIC_SPI 109 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 110 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&clk IMX8MM_CLK_PDM_IPG>,
- <&clk IMX8MM_CLK_PDM_ROOT>;
- clock-names = "ipg_clk", "ipg_clk_app";
- dmas = <&sdma2 24 26 0x80000000>;

Thanks!
[1/1] ASoC: dt-bindings: fsl,micfil: Convert format to json-schema
commit: 02d91fe47100a29a79fcb8798e45c22591ca852d
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
