This causes the PCIe PME and AER root port service drivers to fail their initialization: [ 5.019900] genirq: Setting trigger mode 7 for irq 114 failed (irq_chip_set_type_parent+0x0/0x30) [ 5.028821] pcie_pme: probe of 0001:00:00.0:pcie001 failed with error -22 [ 5.035687] genirq: Setting trigger mode 7 for irq 114 failed (irq_chip_set_type_parent+0x0/0x30) [ 5.044614] aer: probe of 0001:00:00.0:pcie002 failed with error -22 This problem was introduced when the interrupt description was switched from using the GIC directly to using the ICU interrupt controller. Indeed, the GIC has address-cells = <1>, which requires a parent unit address, while the ICU has address-cells = <0>.
