The imx28 RM does not mention i2c clock at all, and I was told by designer that i2c always runs at the same frequency as apbx, which sources from ref_xtal (always 24 MHz). Though there is a divider for apbx clock, it seems every single running system sets the divider as 1 all the time. That said, what I have seen is the i2c clock is always 24 MHz. -- Regards, Shawn -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
