### Device Family

# CC13x2/CC26x2 has to differentiate both pre-RTM and RTM devices. As of now,
# pre-RTM is suffixed with _v1 while RTM is suffixed with _v2. This will be
# removed when CC13x2/CC26x2 RTMs. For now, provide a switch to choose
# either pre-RTM or RTM.
# Also note that the devices name is cc13x2_cc26x2 for all CC13x2/CC26x2
# devices, while the library name is individual for each device family.
