Please let me know if above statement gets you the answer of your question.

I just checked that "qca_btsoc_type" enum contains all the soc type 
which need to be enabled

for BT enablement on the target device. There are few places where logic 
of framing packets transferring

between SoC  and Host depends on the which generation of the chip it is, 
refer api "qca_read_soc_version".

Do you still suggest to sort it here ?
