You're still missing my point here.  What I'm saying is that by using
the slower default ramp rate of the PMIC you're making the length of the
stall in execution introduced by waiting for the ramp to complete more
severe than it needs to be, thus increasing the impact on the system and
the need to do work in software to mitigate that.  Reducing the ramp
time should result in improved system performance.
