12description:
13  The RaspberryPi RP1 is a PCI multi function device containing
14  peripherals ranging from Ethernet to USB controller, I2C, SPI
15  and others.
16  The peripherals are accessed by addressing the PCI BAR1 region.

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