Rockchip mailbox |
|
|
|
The Rockchip mailbox is used by the Rockchip CPU cores to communicate |
|
requests to MCU processor. |
|
|
|
Refer to ./mailbox.txt for generic information about mailbox device-tree |
|
bindings. |
|
|
|
Required properties: |
|
|
|
- compatible: should be one of the following. |
|
- "rockchip,rk3368-mbox" for rk3368 |
|
- reg: physical base address of the controller and length of memory mapped |
|
region. |
|
- interrupts: The interrupt number to the cpu. The interrupt specifier format |
|
depends on the interrupt controller. |

mbox: mbox@ff6b0000 { |
|
compatible = "rockchip,rk3368-mailbox"; |
|
reg = <0x0 0xff6b0000 0x0 0x1000>, |
|
interrupts = <GIC_SPI 146 IRQ_TYPE_LEVEL_HIGH>, |
|
<GIC_SPI 147 IRQ_TYPE_LEVEL_HIGH>, |
|
<GIC_SPI 148 IRQ_TYPE_LEVEL_HIGH>, |
