[PATCH 1/4] arm64: tegra: Add default GIC address cells on Tegra132

From: Krzysztof Kozlowski
Date: Fri Aug 22 2025 - 09:44:08 EST


Add missing address-cells 0 to GIC interrupt node to silence W=1
warning:

tegra132.dtsi:32.3-41: Warning (interrupt_map): /pcie@1003000:interrupt-map:
Missing property '#address-cells' in node /interrupt-controller@50041000, using 0 as fallback

Value '0' is correct because:
1. GIC interrupt controller does not have children,
2. interrupt-map property (in PCI node) consists of five components and
the fourth component "parent unit address", which size is defined by
'#address-cells' of the node pointed to by the interrupt-parent
component, is not used (=0)
