[Sound-open-firmware] What is period_mips used for?

Hi all,

We are trying to figure out what is the difference between Low Latency PCM and Media PCM and we notice that they have different values for SOF_TKN_SCHED_MIPS.

SOF_TKN_SCHED_MIPS translates into period_mips in Linux kernel and firmware. Anyhow, period_mips doesn't look to be used anywhere.

Any idea?
