MUSBMHDRC DRD OTG Controller

The MUSBMHDRC DRD OTG Controller (from now on referred to as MUSB is a Dual-Role OTG IP Core used in several SoC implementations. At the time of this writing at least OMAP, DaVinci and Blackfins integrate that IP Core in the SoC and a discrete version of it is supplied by Texas Instruments as the tusb6010 ASIC.
