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
