Indeed, I forgot to update this file. Thanks a lot for double checking.

+description: |-
+  STMicroelectronics VGxy61 family has a CSI-2 output port. CSI-2 output is a
+  quad lanes 800Mbps per lane.
+  Supported formats are RAW8, RAW10, RAW12, RAW14 and RAW16.
+  Following part number are supported
+  - VG5661 and VG6661 are 1.6 Mpx (1464 x 1104) monochrome and color sensors.
+  Maximum frame rate is 75 fps.
+  - VG5761 and VG6761 are 2.3 Mpx (1944 x 1204) monochrome and color sensors.
+  Maximum frame rate is 60 fps.
