A recently implemented dtc compiler warning reports a dts problem via a build warning: drivers/of/unittest-data/tests-interrupts.dtsi:32.26-35.6: Warning (interrupt_map): /testcase-data/interrupts/intmap1: Missing '#address-cells' in interrupt-map provider The warning will be addressed by a separate patch by suppressing the warning for .dts files that include this .dtsi. This patch documents why the warning is due to a deliberately incorrect .dtsi file so that no one will fix the .dtsi file to prevent the build warning.
