This PR adds support to control the external power output from controllers like nice!nano, nRFMicro etc
I have implemented based on my understanding of Pete suggestion on this feature.
Testing done:
Tested by enabling and disabling the ext_power from application and verified
Verified the application does not crash with boards that does not have ext_power support
Note:
I did not test this in nice!nano since I don't have the boards. Will get help from others once the behavior PR is up
Next Steps:
Create a behavior PR to control enable/disable ext_power
* Add `bt` behavior that can be used to perform certain actions,
such as next/prev identity, reset identity, etc.
NOTE: Multiple identities is only supported for non-split shields,
due to missing Zephyr identity functionality for dual
central/peripheral devices.
* Proper bond reset tied to action, that honors peripheral bonds,
so folks can reset and pair to other hosts, without breaking
bonds between splt halves.
* Add initial event manager implementation,
roughly mimicking Nordic's API.
* Add `position_state_changed` and
`keycode_state_changed` events.
* Hook up HID and keymap to new events
instead of using behaviour global event
crazy.
* Use extra comptible = "zmk,behavior-global" to add
behaviors to global bindings for event notification.
* Implement mod-tap, as a keymap binding and global one
to skip tap if other keycode pressed while held.
