NICE!  

Yes this driver looks to be good enough to use for the 3632 as well.

We would have to extend that driver to support the 3632, add firmware support,
convert the led class registration to the flash LED registration and add the regulator support.

I can abandon the dedicated LED driver and update this one for the 3632.
No reason to have duplicate code.
