   3 Required parent device properties:
   4 - compatible             : contains "stericsson,ab8500";
   5 - interrupts             : contains the IRQ line for the AB8500
   6 - interrupt-controller   : describes the AB8500 as an Interrupt Controller (has its own domain)
   7 - #interrupt-cells       : should be 2, for 2-cell format
   8                             - The first cell is the AB8500 local IRQ number
   9                             - The second cell is used to specify optional parameters
  10                               - bits[3:0] trigger type and level flags:
  11                                   1 = low-to-high edge triggered
  12                                   2 = high-to-low edge triggered
  13                                   4 = active high level-sensitive
  14                                   8 = active low level-sensitive
