| Nordic BELLBOARD |
| |
| BELLBOARD provides support for inter-domain software signaling. It implements |
| a set of tasks and events intended for signaling within an interprocessor |
| communication (IPC) framework. When used in the rx mode, the BELLBOARD |
| instance is used to receive events triggered by other remote cores. |
| |
| Example definition: |
| |
| bellboard: mailbox@deadbeef { |
| compatible = "nordic,nrf-bellboard-rx"; |
| reg = <0xdeadbeef 0x1000>; |
| interrupts = <98 NRF_DEFAULT_IRQ_PRIORITY>, |
| <99 NRF_DEFAULT_IRQ_PRIORITY>; |
| interrupt-names = "irq2", "irq3"; |
| nordic,interrupt-mapping = <0x0000000f 2>, <0x000000f0 3>; |
| #mbox-cells = <1>; |
| }; |
| |
| compatible: "nordic,nrf-bellboard-rx" |
| |

| description: | |
| Set of interrupt mapping pairs. Each pair consists of a bitmask and an |
| interrupt identifier. The bitmask is used to indicate which of the 32 |
| possible events are mapped to the given interrupt. For example, given |
| <0x0000000f 2>, the first four events are mapped to interrupt 2 |
| (irq2). |
