| /** |
| * 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 |
