nordic,nrf-vevif-event-rx
Vendor: Nordic Semiconductor
Note
An implementation of a driver matching this compatible is available in drivers/mbox/mbox_nrf_vevif_event_rx.c.
Description
Nordic VEVIF (VPR Event Interface) - EVENT RX MODE
VEVIF provides support for inter-domain software signaling. It implements a set of events
intended for signaling within the interprocessor communication (IPC) framework.
When used in the event rx mode, the VEVIF events are used to receive IRQs that are
triggered by the VPR core.
Example definition:
cpuppr_vpr: vpr@deadbeef {
...
cpuflpr_vevif_event_rx: mailbox@0 {
compatible = "nordic,nrf-vevif-event-rx";
reg = <0x0 0x1000>;
interrupts = <76 NRF_DEFAULT_IRQ_PRIORITY>;
#mbox-cells = <1>;
nordic,events = <1>;
nordic,events-mask = <0x00008000>;
};
};

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
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
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
List of power states that will disable this device power.
