we used an echo cancellation chip(zl38063) as the sound card for our i.MX6Q customer board.We are referring to the i.MX6ULL scheme, but this chip uses the SAI interface in i.MX6ULL.
the folowing is imx6ull device tree configuration
compatible = "ms,zl38040", "ms,zl38050", "ms,zl38060", "ms,zl38080";
status = "okay";
compatible = "microsemi,microsemi-dac";
i2s-controller = <&sai2>;
because i.MX6Q does't have a SAI interface,so i changed the SAI to SSI.
can SSI replace the SAI interface?
