Subject: [PATCH v5 2/2] bluetooth: hci_bcm: enable IRQ capability from devicetree
Date: Fri, 13 Dec 2019 16:06:22 +0100 [thread overview]
Message-ID: <20191213150622.14162-3-glaroque@baylibre.com> (raw)
In-Reply-To: <20191213150622.14162-1-glaroque@baylibre.com>
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.
