Beware, the top 2 bits are reserved on GICv1, and shouldn't be messed with.
The only time those bits are touched are when the dts is modified with the
bypass flag. Otherwise those bits remain untouched as
The Legacy-IRQ bypass disable and Legacy-FIQ bypass disable is a
feature of GIC-400 and its not X-Gene specific. The only difference in X-Gene
is that we use PPI31 (Legacy-IRQ) for timer and PPI28 (Legacy-FIQ) for perf
Amazing. Someone managed to push the weird-o-meter one level higher.
Any comments on this?

The GIC-400 implementation allows for FIQ and IRQ bypass. In the
X-Gene implementation, the FIQ bypass must be enabled at all time.
Otherwise, some PPI will appear as FIQ and cause kernel problem.

That is not what I was asking about.
The problem with your binding is that it doesn't seem to describe
the hardware structure at all, but rather try to invent devices
because of how it's convenient for how you write the Linux drivers.
This is never a good idea and it will become a problem
