-Subject: [PATCH 140/222] irqchip: bcm2835: Add FIQ support
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add a duplicate irq range with an offset on the hwirq's so the
-driver can detect that enable_fiq() is used.
-Tested with downstream dwc_otg USB controller driver.
