**Power and Clock Management**
Public APIs are provided to perform:
- `Device Management <https://software-dl.ti.com/tisci/esd/latest/2_tisci_msgs/pm/devices.html>'_: Enable and release a module
This configures both power and clock details for the module and keeps track of its usage.

**1. Board Files:** **1. Devicetree bindings:**
Board files are the primary descriptor of the hardware in Zephyr.
**2. Device tree overlays:**
DeviceTree Overlays can be used by the Zephyr application to specify new hardware or re-assign existing hardware described elsewhere in the board files.
**3. Devicetree bindings:**
A devicetree binding declares requirements on the contents of nodes, and provides semantic information about the contents of valid nodes. Zephyr devicetree bindings are YAML files in a custom format (Zephyr does not use the dt-schema tools used by the Linux kernel).
