zephyr,coredump
Vendor: Zephyr-specific binding
Note
An implementation of a driver matching this compatible is available in drivers/coredump/coredump_impl.c.
Description
Pseudo-device to help capturing desired data into core dumps

Designate which type of coredump device this will be.
A device of type COREDUMP_TYPE_MEMCPY can directly memcpy the provided memory-regions
into the coredump. The memory-regions array can contain 0 or more entries, and more
regions can be added at runtime through the coredump_device_register_memory API.
A device of type COREDUMP_TYPE_CALLBACK must specify exactly one entry in the
memory-regions array with a size of 0 and a desired size. The coredump device will
statically allocate a block of memory of the desired size and provide a callback with a
pointer to that memory which will be invoked at the time of a dump. This allows a consumer
to add data into the coredump that may not be directly accessible through a memcpy and/or
provides an opportunity to manipulate data for inclusion in the dump. The
coredump_device_register_memory API is not available for a device of this type.

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.
