Nit: I'd prefer something like the below:
- interrupts: interrupt-specifier for the sole interrupt generated by
the device.

I assume by the name that this is the regulator for the LED that's used
alongside the sensor, rather than for the sensor itself?
Is the LED part of the CM36651 unit, or is it external? I couldn't find
any documentation for the unit.

The vendor prefix looks OK to me. However, it should apper before cavium
to maintain the ordering of the file.
