Title:
dtc crash; pnv_dt_serial cannot find lpc's phandle
Status in QEMU:
Fix
The QEMU project is currently considering to move its bug tracking to another
system. For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch
This assertion should be fixed by upstream commit 8f695676227 "Avoid
assertion in check_interrupts_property()". That should be included in
dtc v1.5.1 which I hope to release soon.

My bad. Yes, you are correct. The problem is seen when decompiling the blob to
source.

True.

IIUC there are two bugs here
1) The powernv machine in qemu is attempting to use a phandle for node
that doesn't have one. It will need to assign a phandle to that node
and re-use it elsewhere. This should be pretty straightforward.
2) dtc is crashing with an assertion - that shouldn't happen,
