Hello everyone：
I am having a problem now, that is：
Want to use DMA to move data from the ssi register into memory，how to operate?
I hope to get some inspiration.
Set ssi like this in my device tree:
ssi2: ssi@0202c000 {
compatible = "fsl,imx6q-ssi","fsl,imx21-ssi";
reg = <0x0202c000 0x4000>;
interrupts = <0 47 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clks IMX6QDL_CLK_SSI2_IPG>,
<&clks IMX6QDL_CLK_SSI2>;
clock-names = "ipg", "baud";
dmas = <&sdma 41 1 0>,
<&sdma 42 1 0>;
dma-names = "rx", "tx";
fsl,fifo-depth = <15>;
fsl,ssi-dma-events = <42 41>;
status = "disabled";
};
Thank you very much!
