arduino-mkr-header
Vendor: Generic or vendor-independent
Description
GPIO pins exposing on Arduino MKR headers.
The Arduino MKR layout provides two headers on both edges of the board.
* One side of the 14-pin header is analog inputs and digital signals.
A1 to A6 is Analog input. The outside pin is AREF.
A0 that is next to AREF used as a DAC output pin too.
D0-D5 is a digital output.
* The other side 14-pin header is power supplies and peripheral interface.
There are 5V and VCC power supply, GND, and RESET pin. UART, I2C,
and SPI peripheral pins are also there. The end 2 pins are simple GPIO pins.
This binding provides a nexus mapping for 22 pins where parent pins 0
through 14 correspond to D0 through D21, and parent pins 15 through 21
correspond to A0 through A6, as depicted below.

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.
|
|
|
List of power states that will disable this device power.
