McPDM module is the interface between the OMAP and TWL6030 audio codec. It transfers data between the two chips using a Pulse Density Modulation protocol, which allows sound to be played or recorded at speeds of up to 96000 Hz. Besides data, McPDM can transfer commands and read status to/from the codec using the frame synchronization line.
Apart from the comments Felipe already made this all looks very good to me - because the McPDM port isn't as general purpose as the McBSP port you can structure things a little more straightforwardly than that driver which will be a relatively big change but apart from that what's here seems reasonable.
