fsl,aud2htx The AUD2HTX is a digital module that provides a bridge between
|
|
the Audio Subsystem and the HDMI RTX Subsystem.
|
|
|
|
Required properties:
|
|
|
|
- compatible: Must contain one of "fsl,imx8mp-aud2htx".
|
|
- reg: Offset and length of the register set for the device.
|
|
- interrupts: <a b> where a is the interrupt number and b is a
|
|
field that represents an encoding of the sense and
|
|
level information for the interrupt. This should be
|
|
encoded based on the information in section 2)
|
|
depending on the type of interrupt controller you
|
|
have.
|
|
- clocks: A list of phandles + clock-specifiers, one for each
|
|
entry in clock-names
|
|
- clock-names: Must contain "bus"
|
|
|
|
Optional properties:
|
|
- dmas: Generic dma devicetree binding as described in
|
|
Documentation/devicetree/bindings/dma/dma.txt.
|
|
- dma-names: One dmas have to be defined, "tx".
|
|
|
|
Example:
|
|
|
|
aud2htx: aud2htx@30cb0000 {
|
|
compatible = "fsl,imx8mp-aud2htx";
|
|
reg = <0x30cb0000 0x10000>;
|
|
interrupts = <GIC_SPI 130 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&audiomix_clk IMX8MP_CLK_AUDIOMIX_AUD2HTX_IPG>;
|
|
clock-names = "bus";
|
|
dmas = <&sdma2 26 2 0>;
|
|
dma-names = "tx";
|
|
power-domains = <&audiomix_pd>;
|
|
status = "disabled";
|
|
};
