* 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
|
||
|
|
|
||
|
|
The AB8500 consists of a large and varied group of sub-devices:
