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