Since the > irqchip patches touch ARM64 Kconfig etc... I'm wondering if it still need to go > through PCI tree. I do not believe there is. These two configure the PCIe controller hardware: PCI: dwc: Determine whether iMSI is used before calling .init PCI: rcar-gen4: Configure AXIINTC if iMSI-RX not used These two fill in GIC ITS quirks: irqchip/gic-v3: Refactor GIC600 limited to 32bit PA erratum handling irqchip/gic-v3: Add Renesas R-Car Gen4 erratum workaround This one does yes depend on the two and two patches above, and can only be applied once all four aforementioned patches land, otherwise things really yes will break: arm64: dts: renesas: r8a779g0: Add GICv3 ITS and update PCIe nodes Would you like me to split the series up , or can you and Marc (?) pick the relevant parts via matching trees ?
