The platform_quirk element in the platform data was used to change the
|
|
way the IRQ is triggered. When set, the EDGE_IRQ quirk would change
|
|
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).
