0001 * Cavium Interrupt Bus widget
0002
0003 Properties:
0004 - compatible: "cavium,octeon-7130-cib"
0005
0006 Compatibility with cn70XX SoCs.
0007
0008 - interrupt-controller: This is an interrupt controller.
0009
0010 - reg: Two elements consisting of the addresses of the RAW and EN
0011 registers of the CIB block
0012
0013 - cavium,max-bits: The index (zero based) of the highest numbered bit
0014 in the CIB block.
0015
0016 - interrupts: The CIU line to which the CIB block is connected.
0017
0018 - #interrupt-cells: Must be <2>. The first cell is the bit within the
0019 CIB. The second cell specifies the triggering semantics of the
0020 line.
