- vtmu-supply: This entry is optional and provides the regulator node supplying
voltage to TMU. If needed this entry can be placed inside
board/platform specific dts file.

+- samsung,tmu_gain: Gain value for internal TMU operation.
+- samsung,tmu_reference_voltage: Value of TMU IP block's reference voltage
