Hello li ang,
Please refer to the attached eDMA test result through Audio interface.
In LS1021 dts file, you could find sai is defined as the following.
sai1: sai@2b50000 {
#sound-dai-cells = <0>;
compatible = "fsl,vf610-sai";
reg = <0x0 0x2b50000 0x0 0x10000>;
interrupts = <GIC_SPI 132 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&platform_clk 1>, <&platform_clk 1>,
<&platform_clk 1>, <&platform_clk 1>;
clock-names = "bus", "mclk1", "mclk2", "mclk3";
dma-names = "tx", "rx";
dmas = <&edma0 1 47>,
<&edma0 1 46>;
status = "disabled";
};
Have a great day,
TIC
