Hi,

This series was triggered by the discussion in [1], and we realized we
need to cleanup the definitions in K3 SoC. Usage of kvm with gic-v2
compatibility is a bit niche usecase, but valid and possible with A53
and A72 even though the GIC500 instantiation is done with no backward
compatibility.

Though GIC ARE option is disabled for no GIC-v2 compatibility,
Cortex-A53 is free to implement the CPU interface as long as it
communicates with the GIC using the stream protocol. This requires
that the SoC integration mark out the PERIPHBASE[1] as reserved area
within the SoC. See longer discussion in [2] for further information.

Update the GIC register map to indicate offsets from PERIPHBASE based
on [3]. Without doing this, systems like kvm will not function with
gic-v2 emulation.

* [PATCH 3/5] arm64: dts: ti: k3-j7200: Fix gic-v3 compatible regs

Though GIC ARE option is disabled for no GIC-v2 compatibility,
Cortex-A72 is free to implement the CPU interface as long as it
communicates with the GIC using the stream protocol. This requires
that the SoC integration mark out the PERIPHBASE[1] as reserved area
within the SoC. See longer discussion in [2] for further information.

Update the GIC register map to indicate offsets from PERIPHBASE based
on [3]. Without doing this, systems like kvm will not function with
gic-v2 emulation.

* [PATCH 5/5] arm64: dts: ti: k3-j721s2: Fix gic-v3 compatible regs

Though GIC ARE option is disabled for no GIC-v2 compatibility,
Cortex-A72 is free to implement the CPU interface as long as it
communicates with the GIC using the stream protocol. This requires
that the SoC integration mark out the PERIPHBASE[1] as reserved area
within the SoC. See longer discussion in [2] for further information.

Update the GIC register map to indicate offsets from PERIPHBASE based
on [3]. Without doing this, systems like kvm will not function with
gic-v2 emulation.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
