Do you mean that the table values are wrong? They should be defined in
the datasheet.

Or if you are trying to change the voltages, you can use the device
tree. See for example rk3288-firefly.dtsi:

regulator-min-microvolt = <850000>;
regulator-max-microvolt = <1350000>;

Then you call regulator_set_value() to set the voltage, or perhaps
regulator_autoset() if there is only one voltage. Or even
regulators_enable_boot_on().
