[PATCH 4/4] arm64: dts: amlogic: s7d: describe the GIC virtualization regions
From: Carlo Caione
Date: Thu Oct 22 2026 - 14:41:25 EST
The S7D device tree describes the distributor and the CPU interface of
the GIC-400, but not its virtual interface control (GICH) and virtual
CPU interface (GICV) regions. Without them the GIC driver does not hand
the GIC over to KVM, which then runs without the in-kernel vGIC.
Describe both regions at their GIC-400 offsets, as S4 does for its
GIC-400 at the same address.
