I added fe_delivery_system_t SYS_DVBT2, but there is no app knowing that yet. Since there is also module param to set DVB-T2 frequencies. For example here is DVB-T2 transmission on channels 570 MHz and 586 MHz. You can just type: echo 570,586 > /sys/module/cxd2820r/parameters/dvbt2_freq as root, or load driver module following way: modprobe cxd2820r dvbt2_freq=570,586 for the same. Also em28xx driver MFE needs review and comments, since I am not sure about its correctness.
