ambiq-header
Vendor: Generic or vendor-independent
Description
GPIO pins exposed on Ambiq Apollo4p EVB headers
The Ambiq Apollo4p EVB layout provides 5x16 and 1x20 pin headers.
The binding provides a nexus mapping for these pins as 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.
|
|
|
List of power states that will disable this device power.
