[PATCH v4 0/5] PCI: rcar-gen4: irqchip/gic-v3: Handle GIC ITS

[Marek Vasut <marek.vasut+renesas@mailbox.org>]

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 (5):
  PCI: dwc: Determine whether iMSI is used before calling .init
  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
