With all the other interesting parametrization in the device tree
I kind of wonder why the PID regulator constants defaults are
not set up from device tree?
Any specific reason?
To me it seems like the kind of stuff userpace will invariably just
get wrong or forget about (somebody just runs a different
distribution without the extra magic to set sysfs right) unless
we supply good defaults.
