William San Filippo commented on MYNEWT-313:
--------------------------------------------
The commit hash 9b008aa849eea2f6dae5f44cc1d523add450b887, while it does help
improve power, is not directly related to this ticket and should not have been
added here. I am not going to move it but it is not related to having drivers
register with the system; it just deals with using a lower power timer on the
nrf52 and changing the value of OS_TICKS_PER_SEC to a more reasonable value.
Hopefully this does not create an issue for folks.

> Project: Mynewt
> Issue Type: New Feature
> Components: BSP, HAL

>
> Need to have drivers support turning on and off based on system power
> settings automatically.Also need someway to semantically look-up initialized
> drivers in the system.
> For this, a device tree is proposed, where drivers register with the system,
> and provide a device ID. This device ID is what the rest of the system uses
> to look up a specific device.
> The OS uses this device list to notify when the system goes into a low power
> state, and the various drivers handle putting the system into a low power
> state.
