currently there are no kernel-enforced limits for the voltage regulator
settings. This means that [root] user can set overvoltages on various parts of
We need something like a table of maximum voltages (for each system revision).
Ideally this should become part of a platform_device private data structure,
something like (per-regulator):
unsigned int flags; /* such as F_DEFAULT_ON */
the voltage setting functions should then not only respect the limits by
pcf50606 hardware, but the limits present in that structure.
