zephyr,ipc-openamp-static-vrings
Vendor: Zephyr-specific binding
Note
An implementation of a driver matching this compatible is available in subsys/ipc/ipc_service/backends/ipc_rpmsg_static_vrings.c.
Description
OpenAMP (RPMsg with static VRINGs) backend
Properties
Properties not inherited from the base binding file.

OpenAMP roles
This property is required. Legal values: |
|
|
phandle to the shared memory region
This property is required. |
|
|
WQ priority for the instance. This property is an array composed by the
priority level and the type of priority (PRIO_COOP for cooperative or
PRIO_PREEMPT for preemptive).
For example for a thread priority K_PRIO_COOP(1) in DT we have
priority = <1 PRIO_COOP>;
or for K_PRIO_PREEMPT(2)
priority = <2 PRIO_PREEMPT>;
When this property is missing a default priority of <0 PRIO_PREEMPT> is
assumed.
|
|
|
The size of the buffer used to send data between host and remote. Default
value is RPMSG_BUFFER_SIZE. This property must be the same for host and
remote and preferably a multiple of the cache line size.
|
Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “zephyr,ipc-openamp-static-vrings” compatible.

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.
