The platform clock divided by 2 or 3 *is* the source clock to the I2C. That's what I'm talking about. > Linux must determine the real > source clock frequency somehow.

That's what I'm proposing, but drop the "i2c-". -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
