The commit 3eb619b2f7d8 ("scripts/dtc: Update to upstream version v1.6.0-11-g9d7888cbf19c") updated dtc version which also contained DTC commit "81e0919a3e21 checks: Add interrupt provider test" where reasons for this checking are mentioned as "A missing #address-cells property is less critical, but creates ambiguities when used in interrupt-map properties, so warn about this as well now." That's why add address-cells property to gic and gpio nodes to get rid of this warning. CC: Andre Przywara <andre.przywara@arm.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com> --- I was grepping DTSes in the kernel and most of them list it as 0. In gicv3 case where its node is added it needs to be filled property that's why also non 0 values are there. Definitely please let me know if 0 is not the right value here.
