Kernel-4.18.0-80.el8_mxs-saif

• Freescale MXS Serial Audio Interface (SAIF)

Required properties:

• compatible: Should be “fsl,-saif”
• reg: Should contain registers location and length
• interrupts: Should contain ERROR interrupt number
• dmas: DMA specifier, consisting of a phandle to DMA controller node
  and SAIF DMA channel ID.
  Refer to dma.txt and fsl-mxs-dma.txt for details.
• dma-names: Must be “rx-tx”.

Optional properties:

• fsl,saif-master: phandle to the master SAIF. It’s only required for
  the slave SAIF.

Note: Each SAIF controller should have an alias correctly numbered
in “aliases” node.

Example:

aliases {
saif0 = &saif0;
saif1 = &saif1;
};

saif0: saif@80042000 {
compatible = “fsl,imx28-saif”;
reg = <0x80042000 2000>;
interrupts = <59>;
dmas = <&dma_apbx 4>;
dma-names = “rx-tx”;
};

saif1: saif@80046000 {
compatible = “fsl,imx28-saif”;
reg = <0x80046000 2000>;
interrupts = <58>;
dmas = <&dma_apbx 5>;
dma-names = “rx-tx”;
fsl,saif-master = <&saif0>;
};
