Subject: Bluetooth: hci_bcm: enable IRQ capability from devicetree
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f25a96c8eb46b86744540ade61c2dbc844c23dbd;p=linux.git

Bluetooth: hci_bcm: enable IRQ capability from devicetree

Add support for getting IRQ directly from DT instead of relying on
converting a GPIO to IRQ. This is needed for platforms with GPIO
controllers that that do not support gpiod_to_irq().
