9678    Implementation notes.
9679 
9680    NTSC/FM AGCs
9681 
9682       Four AGCs are used for NTSC:
9683       (1) RF (used to attenuate the input signal in case of to much power)
9684       (2) IF (used to attenuate the input signal in case of to much power)
9685       (3) Video AGC (used to amplify the output signal in case input to low)
9686       (4) SIF AGC (used to amplify the output signal in case input to low)
9687 
9688       Video AGC is coupled to RF and IF. SIF AGC is not coupled. It is assumed
9689       that the coupling between Video AGC and the RF and IF AGCs also works in
9690       favor of the SIF AGC.
9691 
9692       Three AGCs are used for FM:
9693       (1) RF (used to attenuate the input signal in case of to much power)
9694       (2) IF (used to attenuate the input signal in case of to much power)
9695       (3) SIF AGC (used to amplify the output signal in case input to low)
9696 
9697       The SIF AGC is now coupled to the RF/IF AGCs.
9698       The SIF AGC is needed for both SIF output and the internal SIF signal to
9699       the AUD block.
9700 
9701       RF and IF AGCs DACs are part of AFE, Video and SIF AGC DACs are part of
9702       the ATV block. The AGC control algorithms are all implemented in
9703       microcode.
9704 
9705    ATV SETTINGS
9706 
9707       (Shadow settings will not be used for now, they will be implemented
9708        later on because of the schedule)
9709 
9710       Several HW/SCU "settings" can be used for ATV. The standard selection
9711       will reset most of these settings. To avoid that the end user application
9712       has to perform these settings each time the ATV or FM standards is
9713       selected the driver will shadow these settings. This enables the end user
9714       to perform the settings only once after a drx_open(). The driver must
9715       write the shadow settings to HW/SCU in case:
9716 	 ( setstandard FM/ATV) ||
9717 	 ( settings have changed && FM/ATV standard is active)
9718       The shadow settings will be stored in the device specific data container.
9719       A set of flags will be defined to flag changes in shadow settings.
9720       A routine will be implemented to write all changed shadow settings to
9721       HW/SCU.
9722 
9723       The "settings" will consist of: AGC settings, filter settings etc.
9724 
9725       Disadvantage of use of shadow settings:
9726       Direct changes in HW/SCU registers will not be reflected in the
9727       shadow settings and these changes will be overwritten during a next
9728       update. This can happen during evaluation. This will not be a problem
9729       for normal customer usage.
