[PATCH v5 2/2] bluetooth: hci_bcm: enable IRQ capability from devicetree

From: Guillaume La Roque
Date: Fri Dec 13 2019 - 10:06:33 EST


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.
