Yes, it's GIC-400, thanks for pointing that out. Will fix that in v2.

Nice catch! Actually there is an error (typo?) in SoC's TRM, saying
that Virtual Interface Control Register starts at 0x3000 offset (from
0x12a00000), where it obviously should be 0x4000, that's probably
where this dts error originates from. Btw, I'm also seeing the same
error in exynos7.dtsi. Though I don't have a TRM for Exynos7 SoCs, so
not sure if I should go ahead and fix that too. Anyway, for Exynos850,
I'll fix that in v2 series.

Yeah, after some consideration I removed the whole interrupts header
and used hard-coded values instead. I probably felt it would be right
thing to have, just because there is no public TRM for Exynos850, thus
documenting interrupts somewhere would be nice. But that reasoning is
wrong, as trying to mix that kind of documentation with code just
clutters it. The right thing to do is probably just provide a public
TRM, but that's not for me to decide, alas :) Anyway, will be fixed in
v2.

Ok, will remove that property in v2. Though it looks like CNTFRQ_EL0
register can be only changed in EL3 execution level, so I'll have to
ask the vendor to fix their BL31 or whatever. But that might take some
time, so I'll have to keep "clock-frequency" workaround in my local
tree for now, to make scheduler work.

Checked SoC TRM, there is no PPI for hypervisor virtual timer
interrupt, and no mentioning of it at all. Likewise, I checked ARMv8
ARM and TRM, almost no description of it. Also, I checked other
platforms, and seems like everyone does the same (having only 4
interrupts). And I wasn't able to find any documentation on that, so I
guess I'll leave it as is, if you don't mind.

Yeah, that's just some leftover from vendor's kernel, overlook by
