+/**
+ * kbase_power_model_simple_init - Initialise the simple power model
+ * @kbdev: Device pointer
+ *
+ * The simple power model estimates power based on current voltage, temperature,
+ * and coefficients read from device tree. It does not take utilization into
+ * account.
+ *
+ * The power model requires coefficients from the power_model node in device
+ * tree. The absence of this node will prevent the model from functioning, but
+ * should not prevent the rest of the driver from running.
+ *
+ * Return: 0 on success
+ *         -ENOSYS if the power_model node is not present in device tree
+ *         -EPROBE_DEFER if the thermal zone specified in device tree is not
+ *         currently available
+ *         Any other negative value on failure
