First cell is voltage in microvolts (uV)
Second cell is duty-cycle in percent (%)
+Optional properties for Continuous mode:
+- pwm-dutycycle-unit: Integer value encoding the dutycycle unit. If not
+ defined, <100> is assumed, meaning that
+ pwm-dutycycle-range contains values expressed in
+ percent.
+
+- pwm-dutycycle-range: Should contain 2 entries. The first entry is encoding

+ second one the dutycycle for regulator-max-microvolt.
+ Dutycyle values are expressed in pwm-dutycycle-unit.
+ If not defined, <0 100> is assumed.

NB: To be clear, if voltage-table is provided, then the device will be used
in Voltage Table Mode. If no voltage-table is provided, then the device will
be used in Continuous Voltage Mode.
