This uses the new API for tagging GPIO lines as in use by IRQs. This enforces a few semantic checks on how the underlying GPIO line is used. Only compile tested on the lpc32xx. ChangeLog v2->v3: - Switch to using the startup()/shutdown() callbacks again. Still satisfy the mask/unmask semantics. ChangeLog v1->v2: - Use the .enable() callback from the irq_chip - Call .unmask() from the .enable() callback to satisfy semantics.
