   @acassis Got it, I've added the peripheral support table to the BL808 page 
(moved and expanded from the ox64 page) and created the new config.
   I'll go ahead and mark this as ready for review, but I would still like to 
double check about the ADC conversion return format:
   > Currently, the driver returns unsigned ADC readings on the least 
significant 16 bits of the return data (ie max positive reading of 65535), 
which is the output format for the ADC hardware as configured. From looking at 
other ADC drivers, I saw that some also keep the same output format as provided 
by the hardware, while others return their values shifted left to represent 
signed 32-bit numbers. Is one of these approaches considered standard or 
preferred over the other?
   
   If there is an expected output format for the return values, please let me 
know so I can make sure the driver follows it.
