In order to support Qualcomm ISP hardware architectures that diverge from older architectures, the VFE subdevice driver needs to be refactored to better abstract the different ISP architectures. Gen1 represents the CAMSS ISP architecture. The ISP architecture developed after CAMSS, Titan, will be referred to as Gen2.
