Hi Ian,
> The MINIX NEO Z83-4 and MINIX NEO Z83-4 Pro devices use an AP6255 chip for wifi and bluetooth. Bluetooth requires an ACPI device id of BCM2EA4 with BCM4345 rev C0 firmware.
>
> This patch adds the device id and to use trigger type IRQF_TRIGGER_FALLING as defined by 'GpioInt' in the ACPI DSDT table:
