- vtmu-supply: This entry is optional and provides the regulator node supplying

Following properties are mandatory (depending on SoC):

- samsung,tmu_gain: Gain value for internal TMU operation.

- samsung,tmu_reference_voltage: Value of TMU IP block's reference voltage

- samsung,tmu_noise_cancel_mode: Mode for noise cancellation

- samsung,tmu_efuse_value: Default level of temperature - it is needed when

- samsung,tmu_min_efuse_value: Minimum temperature fused value

- samsung,tmu_max_efuse_value: Maximum temperature fused value

- samsung,tmu_first_point_trim: First point trimming value

- samsung,tmu_second_point_trim: Second point trimming value

- samsung,tmu_default_temp_offset: Default temperature offset
