raspberrypi-40pins-header
Vendor: Generic or vendor-independent
Description
GPIO pins exposed on Raspberry Pi 40-pin header.
The Raspberry Pi layout provides a 2x20 pins header.
This binding provides a nexus mapping for 28 pins 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.
|
|
|
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.
|
|
|
indicates the operational status of a device
