This series does some cleanups, fixes for handling two interrupts getting mapped twice to same crossbar and provides support for hardwired IRQ and crossbar definitions. On certain platforms such as DRA7, SPIs 0, 1, 2, 3, 5, 6, 10, 131, 132, 133 are direct wired to hardware blocks bypassing crossbar. This quirky implementation is *NOT* supposed to be the expectation of crossbar hardware usage. This series adds support to represent such hard-wired irqs through DT and avoid generic allocation/programming of crossbar in the driver. This way of supporting hard-wired irqs was a result of the below discussions. http://www.spinics.net/lists/arm-kernel/msg329946.html Based on 3.15 mainline. All the patches are available here git@xxxxxxxxxx:Sricharanti/sricharan.git crossbar_updates The fixes series[1] earlier posted is merged in to this. [1] http://www.spinics.net/lists/arm-kernel/msg328273.html [V2] Merged the above series and rebased on 3.15 mainline [V3] Modified patch#3 to get irqs-skip properties from DT, merged path#8 for checkpatch warning to other relevant patches and fixed comments for other patches.
