[PATCH] arm64: dts: nuvoton: npcm8xx: Drop the GIC "ppi-partitions" node

[Rob Herring (Arm)]

The Arm GIC "ppi-partitions" node is only relevant to GICv3 and makes no
sense for GICv2 implementations which the GIC-400 is. PPIs in GICv2 have
no CPU affinity.

Thanks, I've applied this to be picked up through the BMC tree.

Hello SoC maintainers,

We have a single devicetree patch for v6.17 for the Nuvoton ARM64 BMC
SoCs. Perhaps it could be picked up as a fix, but I don't consider it
urgent.

Cheers,

Andrew
