This has been requested for the other hwmod conversions as well:
Subject prefix for the arch/arm/mach-omap2/* code should be OMAP: (or
OMAP2+, OMAP3, OMAP4, etc. For this patch, should be something lke
OMAP3: hwmod data: add USB OTG"

As pointed out by Paul on some of the other hwmod conversions, this bit
should be using EN bit, not the GRPSEL mask, namely
