| 2 | |
| 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 |
| 15 | |
| 16 | Optional parent device properties: |
| 17 | - reg : contains the PRCMU mailbox address for the AB8500 i2c port |
| 18 | |
| 19 | The AB8500 consists of a large and varied group of sub-devices: |

| 51 | - interrupt-names : contains names of IRQ resource in the order in which they were |
| 52 | supplied in the interrupts property |
| 53 | - <supply_name>-supply : contains a phandle to the regulator supply node in Device Tree |
