Changes from the previous version from the cover letter
- SPIs and PPIs are numbered starting at 0. Now the gic has it's own irq domain translate function instead of the simple domain one.
- interrupt cell format has changed based on Grant's proposal.
- Dropped "ARM: gic: allow irq_start to be 0". Instead, the first 16 irqs are skipped and the domain irq_base adjusted accordingly.
- Added a fix to of_irq_find_parent when the parent == child.
- Renamed intc_desc.parent to intc_desc.interrupt_parent.
- Implemented Grant's algorithm for walking the list of interrupt controllers. Added a return value to interrupt init functions, so they don't get added to the parent list on a init failure.

Cover letter [PATCH 0/3] GIC OF bindings
From: Rob Herring <[email protected]>
Hopefully, this is the final or near final version of GIC binding support.
Changes from the previous version:
- SPIs and PPIs are numbered starting at 0. Now the gic has it's own irq domain translate function instead of the simple domain one.
- interrupt cell format has changed based on Grant's proposal.
- Dropped "ARM: gic: allow irq_start to be 0". Instead, the first 16 irqs are skipped and the domain irq_base adjusted accordingly.
- Added a fix to of_irq_find_parent when the parent == child.
- Renamed intc_desc.parent to intc_desc.interrupt_parent.
- Implemented Grant's algorithm for walking the list of interrupt controllers. Added a return value to interrupt init functions, so they don't get added to the parent list on a init failure.
The changes are significant enough that I did not include previous acked/reviewed/tested-by's.
