Subject: [PATCH] bluetooth: hci_bcm: enable IRQ capability from node
Date: Wed,  4 Dec 2019 08:14:11 +0100
Message-ID: <20191204071411.13624-1-glaroque@baylibre.com> (raw)

Actually IRQ can be found from GPIO but all platorms 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
field in node and support it in driver.
