DT-enabled kernel should have a CPU node connected to a clock. This clock is the CCOUNT clock. Use old platform_calibrate_ccount call as a fallback when CPU node cannot be found or has no clock and in non-DT-enabled configurations. Drop no longer needed code that updates CPU clock-frequency property in the DT; drop DT-related code from the platform_calibrate_ccount too. Move of_clk_init to the top of time_init, so that clocks are initialized before CCOUNT calibration is attempted. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
