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.
