B (SPRUGR0B) Figure 14-20 "UART Functional Integration" and Table 14-11 "UART Clocks", all of the UARTs appear to have independent functional clocks. The table even mentions a CM_FCLKEN1_CORE.EN_UART4 bit. But the PRCM chapter of this TRM doesn't mention that at all. So the documentation is not too useful here. On the rest of the OMAPs, as far as I know, the UART clocks are all separate. - Paul
