Re: [PATCH 03/12] mtd: nand: omap: Move IRQ handling from GPMC to NAND driver

* Roger Quadros [off-list ref] [150710 05:26]:

Since the Interrupt Events are used only by the NAND driver,
there is no point in managing the Interrupt registers
in the GPMC driver and complicating it with irqchip modeling.

I don't think it's a good idea to allow external drivers to
tinker directly with GPMC registers. How about just set up GPMC
as an irqchip for the edge detection interrupts?

I think we already have devices with multiple NAND chips. And
there's nothing stopping other drivers from using the edge
detection interrupts.
