Subject[PATCH v5 2/2] bluetooth: hci_bcm: enable IRQ capability from devicetree
Date
Actually IRQ can be found from GPIO but all platforms don't support
gpiod_to_irq, it's the case on amlogic chip.
so to have possibility to use interrupt mode we need to add interrupts
property in devicetree and support it in driver.
