Per the binding, omitting the clock frequency from a Geni I2C controller node defaults the bus to 100Khz. But at least in Linux, a friendly info print highlights the lack of explicitly defined frequency in the DeviceTree. Specify the frequency, to give it an explicit value, and to silence the log print in Linux.
