16 currently two distinct major versions of the 16 currently two distinct major versions of the IP that is supported
17 by a single driver. The IP versions are name 17 by a single driver. The IP versions are named v1 and v2, v1 is
18 for i.MX8MM which has ONLY 1 sensor, v2 is f 18 for i.MX8MM which has ONLY 1 sensor, v2 is for i.MX8MP which has
19 2 sensors. 19 2 sensors.
