Subject: [PATCH v2] bluetooth: hci_bcm: enable IRQ capability from node
Date: Wed,  4 Dec 2019 17:12:39 +0100
Message-ID: <> (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.

Signed-off-by: Guillaume La Roque <>
sorry for noise,

v2 is for rebasing on master branch
