GPMC dummy chip is being modified to so that irq descriptors are created
dynamically [1], with a final goal of reaching something similar to [2],
please let me know if any comments on those.

Hi Ming,

Requesting irq is called by driver of IP, while whether it is shared or
not depends on SoC where IP lives, so ideally it seems platform should
inform the driver whether it is shared & driver should do what platform
tells. Or else to be safe, it should be made shared always ?

This may not make much sense now w.r.t gpmc, but would be applicable
once gpmc becomes a driver (undergoing conversion), but may not be that
important as there are no SoCs presently sharing gpmc interrupt (afaik)

Afzal
