occheung 3ed6a7ccbe 2118-2128: fix data rate spec
Quoted from the isolator datasheet: "Data rates up to 150 Mbps are supported."
Saying the maximum data rate is at least 150 Mbps is not very accurate.

occheung d622423675 4456: remove mention to cpld cfg on rf_sw
As communication to ALmazny mezzanine does not use bitbang anymore, there is very little value for routing LVDS signal.
Also, MUXOUT readout from ADF5356 has an easily understandable API available.
So there should not be any reasons to use EEM[4:8] for anything other than controlling RF switches.

occheung d4387cae18 5108: fix d157dda
Made the spectrometer thing more stright forward. It really just monitors the laser power in that use case.

occheung 1b8beee45d 2118-2128: add max data rate spec
Base on the isolator datasheet, where it stated that "Data rates up to 150 Mbps are supported".
The electrical specific of the datasheet stated the spec differently.

occheung 389b97d9e4 5108: make ADC-Repeaters-EEM path unidirectional
The only signal that enters the ADC through the repeaters is the SPI clock.
It is only a state/time reference, no meaning info goes through this path.

occheung 5c962c64d4 5432: ditch import statement in python
Obviously, the import statements cannot be put right before the methods in the same indentation.
It was there because there wasn't a better way to put these code.
Now, it is replaced with an worded instruction that imports are needed.
