+When running with DT, we no longer have a board file that can set up the
+platform data for wlcore. Allow this data to be passed from DT.
+
+Since some platforms use a gpio-irq, add support for passing either the
+irq number or the gpio number. For the latter case, the driver will
+request the gpio and convert it to the irq number. If an irq is
+specified, it'll be used as is.

+the device is released. Dereference to our private data first.]

-The platform_quirk element in the platform data was used to change the

-the irqflags used and treat edge trigger differently from the rest.
-
-Instead of hiding this irq flag setting behind the quirk, have the
-board files set the flags during initialization.  This will be more
-meaningful than driver-specific quirks when we switch to DT.
-
-Additionally, fix missing gpio_request() calls in the boarding files
-(so that setting the flags actually works).
