raspberrypi,pico-header-r3
Vendor: Raspberry Pi Foundation
Description
GPIO pins exposed on Raspberry Pi Pico (R3) headers.
The Pico layout provides two headers, one each along opposite edges
of the board.
Proceeding counter-clockwise:
* A 20-pin header. 16 pins on this header are exposed by this binding.
* A 20-pin header. 10 pins on this header are exposed by this binding.
This binding provides a nexus mapping for 26 pins where parent pins 23
through 25 correspond to ADC0 through ADC2, and parent pins 0 through 22
correspond as depicted below:
0 GP0 VBUS -
1 GP1 VSYS -
- GND GND -
2 GP2 3V3_EN -
3 GP3 3V3_OUT -
4 GP4 ADC_REF -
5 GP5 ADC2/GP28 25
- GND AGND/GND -
6 GP6 ADC1/GP27 24
7 GP7 ADC0/GP26 23
8 GP8 RUN -
9 GP9 GP22 22
- GND GND -
10 GP10 GP21 21
11 GP11 GP20 20
12 GP12 GP19 19
13 GP13 GP18 18
- GND GND -
14 GP14 GP17 17
15 GP15 GP16 16

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.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
List of power states that will disable this device power.

|
|
indicates the operational status of a device
