nordic,nrf-bellboard-rx
Vendor: Nordic Semiconductor
Note
An implementation of a driver matching this compatible is available in drivers/mbox/mbox_nrf_bellboard_rx.c.
Description
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>;
};

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).

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.
