SIF AGC is not coupled. It is assumed 9688 that the coupling between Video AGC and the RF and IF AGCs also works in 9689 favor of the SIF AGC. 9690 9691 Three AGCs are used for FM: 9692 (1) RF (used to attenuate the input signal in case of to much power) 9693 (2) IF (used to attenuate the input signal in case of to much power) 9694 (3) SIF AGC (used to amplify the output signal in case input to low) 9695 9696 The SIF AGC is now coupled to the RF/IF AGCs. 9697 The SIF AGC is needed for both SIF output and the internal SIF signal to 9698 the AUD block. 9699 9700 RF and IF AGCs DACs are part of AFE, Video and SIF AGC DACs are part of 9701 the ATV block. The AGC control algorithms are all implemented in 9702 microcode. 9703 9704 ATV SETTINGS 9705 9706 (Shadow settings will not be used for now, they will be implemented 9707 later on because of the schedule) 9708 9709 Several HW/SCU "settings" can be used for ATV. The standard selection 9710 will reset most of these settings. To avoid that the end user application 9711 has to perform these settings each time the ATV or FM standards is 9712 selected the driver will shadow these settings. This enables the end user 9713 to perform the settings only once after a drx_open(). The driver must 9714 write the shadow settings to HW/SCU in case: 9715 ( setstandard FM/ATV) || 9716 ( settings have changed && FM/ATV standard is active) 9717 The shadow settings will be stored in the device specific data container. 9718 A set of flags will be defined to flag changes in shadow settings. 9719 A routine will be implemented to write all changed shadow settings to 9720 HW/SCU. 9721 9722 The "settings" will consist of: AGC settings, filter settings etc. 9723 9724 Disadvantage of use of shadow settings: 9725 Direct changes in HW/SCU registers will not be reflected in the 9726 shadow settings and these changes will be overwritten during a next 9727 update. This can happen during evaluation. This will not be a problem 9728 for normal customer usage. 9729 */ 9730 /* -------------------------------------------------------------------------- */ 9731 9732 /* 9733 * \fn int power_down_atv () 9734 * \brief Power down ATV. 9735 * \param demod instance of demodulator 9736 * \param standard either NTSC or FM (sub strandard for ATV ) 9737 * \return int. 9738 * 9739 * Stops and thus resets ATV and IQM block 9740 * SIF and CVBS ADC are powered down 9741 * Calls audio power down 9742 */ 9743 static int 9744 power_down_atv(struct drx_demod_instance *demod, enum drx_standard standard, bool primary) 9745 { 9746 struct i2c_device_addr *dev_addr = demod->my_i2c_dev_addr;
