ipa: raspberrypi: First version of autofocus algorithm using PDAF
Provide the first version of the Raspberry Pi autofocus algorithm. This implementation uses a hybrid of contrast detect autofocus (CDAF) and phase detect autofocus (PDAF) statistics. PDAF is always preferred over CDAF due to having less "hunting" behavior.
