GTA02 vibrator uses FIQ-based PWM, so that's not needed for GTA02 if it
PWM broke and nobody had time to fix it, so Matt just set it to GPIO IIRC.
There's actually a good reason now to think again about some kind of PWM
on one LED anyway, we discovered at least some GTA02 A5 in the field
have the LED drive issue on red. PWM is actually a valid workaround for
But we expect PWM2 that would drive red LED to be repurposed for
tickless clock stuff by Andrzej. So we could do LED PWM in FIQ same way
