[PATCH 1/4] arm64: dts: amlogic: s7: fix the GIC CPU interface region size

From: Carlo Caione

Date: Thu Oct 22 2026 - 14:32:13 EST


The CPU interface of the GIC-400 spans 8 KiB, but the S7 device tree
describes only its first 256 bytes. The GIC driver then disables the
split priority drop and deactivation mode, which needs the GICC_DIR
register in the second 4 KiB page, and warns at boot:

[ 0.000000] GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set

Describe the whole 8 KiB region, as the other Amlogic SoCs with a
GIC-400 at the same address do.

Fixes: 1b753fcfcff8 ("arm64: dts: add support for S7 based Amlogic BP201")
