- * 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:
- Device IRQ Names Supply Names Description

- 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
