zephyr,priority:

type: array

description: |
|
|
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.

description: |

The size of the buffer used to send data between host and remote. Default
