The same issue exists on OMAP5 as on OMAP4:
commit 12d82e4b0aa6c71f38b668a372f9a13f243207da
Author: Peter Ujfalusi <peter.ujfalusi@xxxxxx>

ARM: OMAP4: hwmod_data: Correct IDLEMODE for McPDM
McPDM need to be configured to NO_IDLE mode when it is in used otherwise
vital clocks will be gated which results 'slow motion' audio playback.
