Why is that ? There are interrupts of LOW_LEVEL type on OMAP and this change break those. Regards Santosh ^ permalink raw reply [flat|nested] 2+ messages in thread

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: http://infocenter.arm.com/help/topic/com.arm.doc.ihi0048a/CACCAGCF.html ^ permalink raw reply [flat|nested] 2+ messages in thread
