[PATCH v2 0/4] PCI: rcar-gen4: irqchip/gic-v3: Handle GIC ITS

[Marek Vasut]

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.
