particle-gen3-header
Vendor: Generic or vendor-independent
Description
GPIO pins exposed on Particle Gen3 (Feather) headers.
The Particle Gen3 boards are compatible with the Adafruit Feather
"shields" but use a different orientation and pin numbering scheme.
With the board oriented with the micro USB at the top:
* A 12-pin header on the right. 9 pins on this header are exposed
by this binding
* A 16-pin header. 13 pins on this header are exposed by this
binding.
This binding provides a nexus mapping for 22 pins where parent pins
0 through 8 correspond to the pins on the 12-pin header, starting
from the bottom; and pins 9 through 21 correspond to pins on the
16-pin header, skipping the bottom pin then assigning 9 through 19,
skipping over GND, and replacing the lower 3V3 with pin 20. The
physical layout is depicted below.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
