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

or bus operates, measured in Hertz (Hz). This value is crucial for configuring
|
|
hardware components that require a specific clock speed.
