Hi,

The defconfig for OMAP2+ now have the CPU_IDLE enabled which can cause audio
artifacts because we try to enter too low power state from where the wakeup
takes longer than the FIFO can tolerate on the dai side.

While adding pm_qos to McPDM and DMIC I have noticed that the McBSP calculation
was not correct as we need usec for the latency value.

Regards,
Peter
