Thanks.

And this is exactly how the regulator API work:

static inline int regulator_set_voltage_tol(struct regulator *regulator,
int new_uV, int tol_uV)
{
if (regulator_set_voltage(regulator, new_uV, new_uV + tol_uV) == 0)
return 0;
else
return regulator_set_voltage(regulator,
new_uV - tol_uV, new_uV + tol_uV);
}



But yeah, OPP-v2 is going to take care of this with target/min/max
values..
