[PATCH 2/4] arm64: dts: amlogic: s7d: fix the GIC CPU interface region size

From: Carlo Caione

Date: Thu Oct 22 2026 - 14:33:27 EST


The CPU interface of the GIC-400 spans 8 KiB, but the S7D 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 that the range is
too small.

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