				should be 4 for SUPER_TURBO or 3 for TURBO

- qcom,pvs-init-voltage:  	A list of integers whose length is equal to 2

				to the power of qcom,pvs-fuse[num-of-bits]. The

				location or 0-based index of an element in the

				of the PVS bin in SVS, NOM and Turbo corner in microvolts.

				The location or 0-based index of an triple in the
