[PATCH 0/8] A new set of Linux OD interfaces

[Evan Quan]

The existing OD interface `pp_od_clk_voltage` is unable to meet the growing
demands for more OD functionalities. Since the buf used within it comes with
size limit as one page. With more OD functionalities added, we will hit that
limit soon.

To better meet the growing demainds, a new set of OD interfaces are designed.
With this new design, there will be multiple interfaces exposed with each
representing a single OD functionality. And all those interfaces will be
arranged in a tree liked hierarchy as below. Meanwhile all functionalities
for the same component will be arranged under the same directory.

gpu_od/
├── fan_ctrl
    ├── acoustic_limit_rpm_threshold
    ├── acoustic_target_rpm_threshold
    ├── fan_curve
    ├── fan_minimum_pwm
    ├── fan_mode
    ├── fan_target_temperature
...
...(more to be added)
