Side note: unrelated to this patch: PMICs have discrete step sizes of 10mV, 12.5, 25mV etc.. which makes something lik 1.118V probably not exactly possible on a PMIC with 25mV step. We need to next probably create a framework to round_up the voltages to the PMIC step size once the PMIC voltage layer changes are in.
