Rabin,

As part of the commit 5c0c1f08a (gic: implement set_type)
change, I see that you are ignoring interrupts which
are of LOW_LEVEL type. Why is that ?

There are interrupts of LOW_LEVEL type on OMAP and this
change break those.

Regards
Santosh

Please see the discussion on an earlier, similar patch:
https://patchwork.kernel.org/patch/75509/.  The discussion did
not move further at that time and the "rather easy" solution
mentioned there was implemented.

The GIC spec seems to only talk about rising-edge and active
high:
