The I2C clock is only visible to the I2C devices. The system clock is seen by many devices.

That's why I don't think the divider belongs in the device tree. Just put the actual resulting clock frequency in the device tree. Besides, putting that snippet in the platform driver *is* exposing it. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
