5  Nordic VEVIF (VPR Event Interface) - TASK RX MODE
6
7  VEVIF is an event interface for VPR, allowing connection to the domain's DPPI
8  system. VEVIF can also generate IRQs to other CPUs.
9
10  VEVIF provides support for inter-domain software signaling. It implements a set of tasks
11  intended for signaling within an interprocessor communication (IPC) framework.
12  When used in task rx mode, the VEVIF tasks are used to receive events triggered by other core.
13
14  Example definition:
15
16    cpuppr: cpu@d {
17      ...
18      cpuppr_vevif_task_rx: mailbox {
19        compatible = "nordic,nrf-vevif-task-rx";
20        interrupts = <0 NRF_DEFAULT_IRQ_PRIORITY>,
21                     <1 NRF_DEFAULT_IRQ_PRIORITY>,
22                     ...
23                     <N NRF_DEFAULT_IRQ_PRIORITY>;
24        #mbox-cells = <1>;
25        nordic,tasks = <16>;
26        nordic,tasks-mask = <0xfffffff0>;
27      };
