On tx2 board，the original frequency of DMIC3 is 3072000, i want to change it to 2048000(2MHz),
- modify assigned-clock-rates = <3072000> in tegra_dmic3 node in tegra186-soc-base.dtsi file as <2048000>;
- recompile and upgrade to board, then reboot;
but when I use record command to capture, the dmic3 clock is still 3MHz;
How to change clock rate of DMIC3?
