Description

Nordic VEVIF (VPR Event Interface) - Local

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

Example definition:

  cpuppr: cpu@d {
    ...
    cpuppr_vevif_local: mailbox {
      compatible = "nordic,nrf-vevif-local";
      interrupts = <0 NRF_DEFAULT_IRQ_PRIORITY>,
                   <1 NRF_DEFAULT_IRQ_PRIORITY>,
                   ...
                   <N NRF_DEFAULT_IRQ_PRIORITY>;
      #mbox-cells = <1>;
      nordic,tasks = <16>;
      nordic,tasks-mask: <0xfffffff0>;
    };
  };

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`#mbox-cells`	`int`	Number of items to expect in a Mailbox specifier This property is required.
`nordic,tasks`	`int`	Number of tasks supported by the VEVIF instance. This property is required.
`nordic,tasks-mask`	`int`	Mask of tasks supported by the VEVIF instance. This property is required.

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nordic,nrf-vevif-local” compatible.

Name	Type	Details
`wakeup-source`	`boolean`	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.
`power-domain`	`phandle`	Power domain the device belongs to. The device will be notified when the power domain it belongs to is either suspended or resumed.
`zephyr,pm-device-runtime-auto`	`boolean`	Automatically configure the device for runtime power management after the init function runs.
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg`	`array`	register space See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device This property is required. See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information. This property is deprecated.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`zephyr,deferred-init`	`boolean`	Do not initialize device automatically on boot. Device should be manually initialized using device_init().
