Subject[PATCH v6 2/6] dt-bindings: PCI: renesas,pci-rcar-gen2: Add device tree support for r9a06g032
Date
Add internal PCI bridge support for the r9a06g032 SOC. The Renesas
RZ/N1D (R9A06G032) internal PCI bridge is compatible with the one
present in the R-Car Gen2 family.
Compared to the R-Car Gen2 family, it needs three clocks instead of
one.

The 'resets' property for the RZ/N1 family is not required.
