LTC4291-1 + LTC4292 Software Interface datasheet and sample code

Hi Sir

I am a distributor Anstek FAE in Taiwan.  My customer will design use LTC4291-1 + LTC4292 for 4 port  smart PSE BT product. 

They need to customize each one to dynamically adjust the output power.

Does ADI have a reference source code for they specification?

If no any reference source code for dynamically adjust power.

Where should I find these documentation about registers ,programming and sample code , provide to my customer ?

Thanks.
