1 * AB8500 Multi-Functional Device (MFD)
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
16 The AB8500 consists of a large and varied group of sub-devices:
