| description: |
| The RaspberryPi RP1 is a PCI multi function device containing |
| peripherals ranging from Ethernet to USB controller, I2C, SPI |
| and others. |
| The peripherals are accessed by addressing the PCI BAR1 region. |

| Specifies respectively the interrupt number and flags as defined |
| in include/dt-bindings/interrupt-controller/irq.h. |
| Since all interrupts are active high, only IRQ_TYPE_LEVEL_HIGH |
| and IRQ_TYPE_EDGE_RISING can be specified as type flags. |
| The supported values for the interrupt number are: |
