56 * During kernel bootup, the SoC runs at 800MHz with 875mV set by the bootloaders.
57 * During regulator registration, kernel not knowing the initial voltage,
58 * considers it as zero and brings up the regulators with minimum supported voltage.
59 * Update the regulator-min-microvolt with SVS voltage of 725mV so that
60 * the regulators are brought up with 725mV which is sufficient for all the
61 * corner parts to operate at 800MHz
