zephyr,ipc-openamp-static-vrings

Vendor: Zephyr-specific binding

Description

OpenAMP (RPMsg with static VRINGs) backend

Properties

Node specific properties

Deprecated node specific properties

Base properties

Properties not inherited from the base binding file.

Name

Type

Details

role

string

 
OpenAMP roles

This property is required.

Legal values: 'host', 'remote'

memory-region

phandle

 
phandle to the shared memory region

This property is required.

zephyr,priority

array

 
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_COOP> is
assumed.

Deprecated properties not inherited from the base binding file.

(None)

boolean

 
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

Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.

The device will be notified when the power domain it belongs to is either
