Configure all R-Car Gen4 PCIe controller MSI registers fully, both in
case MSI are enabled and disabled.
Patch GIC ITS driver and add quirks for R-Car Gen4 GIC ITS, which is
configured to 32-bit address width for AXI or APB interface.
Switch R-Car V4H to use GIC ITS in its DT and describe the GIC ITS
implementation cacheable and shareable limitations.
Marek Vasut (4):
PCI: rcar-gen4: Configure AXIINTC if iMSI-RX not used
irqchip/gic-v3: Refactor GIC600 limited to 32bit PA erratum handling
irqchip/gic-v3: Add Renesas R-Car Gen4 erratum workaround
arm64: dts: renesas: r8a779g0: Add GICv3 ITS and update PCIe nodes
