Not just that. For example if two supplies are present in CPU node like:
ABC-supply and XYZ-supply. And the values present in OPP node are like:
opp00 {
opp-hz = /bits/ 64 <1700000000>;
/* ABC supply XYZ supply */
opp-microvolt = <1300000 1300000 1300000>, <1400000 1400000 1400000>;
opp-microamp = <70000>;
clock-latency-ns = <30>;
opp-suspend;
};
Then the code can get regulators with those names (ABC and XYZ), but it can't
figure out which triplet in the "opp-microvolt" property belongs to which
supply.
I am working on some solution to that, but wanted to keep the entire series self
sufficient and so removing the leftovers first in this patch.
