3*c66ec88fSEmmanuel VadotRequired properties:
4*c66ec88fSEmmanuel Vadot
5*c66ec88fSEmmanuel Vadot- compatible : should be "opencores,or1k-pic-level" for variants with
6*c66ec88fSEmmanuel Vadot  level triggered interrupt lines, "opencores,or1k-pic-edge" for variants with
7*c66ec88fSEmmanuel Vadot  edge triggered interrupt lines or "opencores,or1200-pic" for machines
8*c66ec88fSEmmanuel Vadot  with the non-spec compliant or1200 type implementation.
9*c66ec88fSEmmanuel Vadot
10*c66ec88fSEmmanuel Vadot  "opencores,or1k-pic" is also provided as an alias to "opencores,or1200-pic",
11*c66ec88fSEmmanuel Vadot  but this is only for backwards compatibility.
12*c66ec88fSEmmanuel Vadot
13*c66ec88fSEmmanuel Vadot- interrupt-controller : Identifies the node as an interrupt controller
14*c66ec88fSEmmanuel Vadot- #interrupt-cells : Specifies the number of cells needed to encode an
15*c66ec88fSEmmanuel Vadot  interrupt source. The value shall be 1.
