| |
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 since there is no reset-controller support yet for the RZ/N1 family.
