Under device tree this should be done as an interrupt. You only > (currently) need the dubious frig with gpios for ACPI I think. Using the gpios declared like this, it will go the same code path as the ACPI. I wasn't sure which to list in the optional properties, so I used gpios because the other magnetometer device tree bindings listed also gpios. It is better to specify the interrupt directly since it will be handled by the core, so I will remove gpios and list interrupts instead.
