[PATCH V3 00/16] irqchip: crossbar: driver fixes
r.sricharan at ti.com
Mon Jun 16 04:23:00 PDT 2014
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.
Based on 3.15 mainline.
All the patches are available here
git at github.com:Sricharanti/sricharan.git crossbar_updates
The fixes series earlier posted is merged in to this.
[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.
