|
||||
Optional properties:
|
||||
|
||||
- interrupt-parent : phandle to the parent interrupt controller
|
||||
- interrupts : interrupt mapping for GPIO IRQ
|

Example:
|
||||
|
||||
bmc150_magn@12 {
|
||||
compatible = "bosch,bmc150_magn";
|
||||
reg = <0x12>;
|
||||
interrupt-parent = <&gpio1>;
|
