Specify the default mux and divider clocks in device tree to ensure the FIMC devices on Trats, Trats2, Universal_c210 and Odroid X2/U3 boards are clocked from recommended clock source and with maximum supported frequency. For Trats2 also the MIPI-CSIS and the camera sensor clocks are configured, the 'clock-frequency' property is deprecated in favour of 'assigned-clock-rates' property.
