[PATCH 02/10] arm64: dts: fsl-ls1043a: Add default GIC address cells
Posted by Krzysztof Kozlowski 1 month, 1 week ago
Add missing address-cells 0 to GIC interrupt node to silence W=1
warning:

  fsl-ls1043a.dtsi:330.5-342.26: Warning (interrupt_map): /soc/scfg@1570000/interrupt-controller@1ac:interrupt-map:
    Missing property '#address-cells' in node /interrupt-controller@1400000, 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)
