After the commit abc0b1447d49 ("drm: Perform basic sanity checks on probed modes"), proper clock-frequency becomes mandatory for validating the mode of panel. The display does not work if there is no mode validated. Also, this clock-frequency must be set appropriately for getting required frame rate.
