Debugging features:
MODULATOR_STATUS and MODULATOR_RESET have been added to debug
possible problems with too high temperatures (overtemperature)
or PLL lock loss on FSM type cards.
The MODUALTOR_STATUS property returns a __u32 with the following status bits:
- bit 0 : Lock status 1=lock OK, 0 = lock lost
- bit 1 : Sticky lock lost indicator
0 = no PLL lock loss since last status read
1 = lock has been lost since last status read
- bit 2 : 0 = no overtemperature
1 = overtemperature detected
The MODULATOR_RESET property can be used to reset the modulator without
needing to reload the driver or rebooting.
All channels should be stopped before using it and restarted after using it.
Otherwise, results are unpredictable.
