On S2MPS11 device, the buck7 and buck8 regulator voltages start at 750 mV, not 600 mV. Using wrong minimal value caused shifting of these regulator values by 150 mV (e.g. buck7 usually configured to v1.35 V was reported as 1.2 V).
On most of the boards these regulators are left in default state so this was only affecting reported voltage. However if any driver wanted to change them, then effectively it would set voltage 150 mV higher than intended.
