Description

Nordic VEVIF (VPR Event Interface) - TASK TX MODE

VEVIF is an event interface for VPR, allowing connection to the domain's DPPI
system. VEVIF can also generate IRQs to other CPUs.

VEVIF provides support for inter-domain software signaling. It implements a set of tasks
intended for signaling within an interprocessor communication (IPC) framework.
When used in task tx mode, the VEVIF tasks are used to trigger IRQs on VPR core.

Example definition:

  cpuppr_vpr: vpr@deadbeef{
    ...
    cpuppr_vevif_task_tx: mailbox@0 {
      compatible = "nordic,nrf-vevif-task-tx";
      reg = <0x0 0x1000>;
      #mbox-cells = <1>;
      nordic,tasks = <16>;
      nordic,tasks-mask = <0xfffffff0>;
    };
  };
