DSP node on the Linux kernel side must also take care of enabling DAI/DMA related clocks. By design we choose to manage DAI/DMA clocks from the kernel side because of the architecture of some i.MX8 boards. Clocks are handled by a special M4 core which runs a special firmware called SCFW (System Controler firmware). This communicates with A cores running Linux via a special Messaging Unit and implements a custom API which is already implemented by the Linux kernel i.MX clocks implementation. Note that these clocks are optional. We can use the DSP without them.
