Commit de09e4555592986219132b518c3f7834a28823cd in the mainline does that. Then, if using DSI PLL, the clock routing needs to be fixed for OMAP5, mainline commit f8ad984ce0372f43006f5c700310c2d6f301085d does that. I'm not sure if there are any other OMAP5 DPI specific things, those are the ones I remember.
