| * 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 |
| |
| Optional parent device properties: |
| - reg : contains the PRCMU mailbox address for the AB8500 i2c port |
| |
| The AB8500 consists of a large and varied group of sub-devices: |
| |

| Required child device properties: |
| - compatible : "stericsson,ab8500-[bm|btemp|charger|fg|gpadc|gpio|ponkey| |
| pwm|regulator|rtc|sysctrl|usb]"; |
| |
| Optional child device properties: |
| - interrupts : contains the device IRQ(s) using the 2-cell format (see above) |
| - interrupt-names : contains names of IRQ resource in the order in which they were |
| supplied in the interrupts property |
| - <supply_name>-supply : contains a phandle to the regulator supply node in Device Tree |
