The interrupt-map property used in the description of the Marvell Armada 7K/8K PCIe controllers has a bogus extraneous 0 that causes the interrupt conversion to not be done properly. 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>.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
