But the DTS file might be changed to use clock-frequency.
In my opinion implementing "backward compatilility" for MPC5121 is not good idea. MPC5121 I2C support is completly new thing in mainline. Simply, there is no DTS with which I have to be compatible. Adding backward compatibility with nothing may be confusing. -- Best Regards, Piotr Zięcik -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
