Better, thanks.

Ok, so is it single-LED driver, or can it driver ir & white LEDs at
the same time?

Is this realistic config? I'd expect flash to use more power than
torch, and would expect longer timeout than 0.8msec.

Also.. if this is physically one white LED, it should not be
spread over reg = <0> and reg = <1>...

Best regards,
