 12description:
 13  For UHS devices which require tuning, the device tree should have a
 14  cpu_thermal node which maps to the appropriate thermal zone. This
 15  is used to get the temperature of the zone during tuning.

121    description:
122      It represents the speed at which a clock signal associated with a device
123      or bus operates, measured in Hertz (Hz). This value is crucial for configuring
124      hardware components that require a specific clock speed.
