Subject: [PATCH 1/4] arm64: dts: exynos5433: Add default GIC address cells
Add missing address-cells 0 to GIC interrupt node to silence W=1
warning:
exynos5433-tm2-common.dtsi:1000.2-41: Warning (interrupt_map):
/soc@0/pcie@15700000:interrupt-map:
Missing property '#address-cells' in node /soc@0/interrupt-
controller@11001000, using 0 as fallbac
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).
