This driver supports multiple architecture versions of the Qualcomm ISP. The CAMSS architecure which this driver is name after, and with the introduction of this series, the Titan architecture. The ISPIF is an IP-block that is only present in the CAMSS generation of the architecture. In order to support the Titan generation, make the ISPIF an optional subdevice.
