MEMBERS

info

pointer to struct analog_demod_info

set_params

callback function used to inform the demod to set the demodulator parameters needed to decode an analog or radio channel. The properties are passed via struct analog_params;.

has_signal

returns 0xffff if has signal, or 0 if it doesn't.

get_afc

Used only by analog TV core. Reports the frequency drift due to AFC.

tuner_status

callback function that returns tuner status bits, e. g. TUNER_STATUS_LOCKED and TUNER_STATUS_STEREO.

standby

set the tuner to standby mode.

release

callback function called when frontend is dettached. drivers should free any allocated memory.

i2c_gate_ctrl

controls the I2C gate. Newer drivers should use I2C mux support instead.

set_config

callback function used to send some tuner-specific parameters.
