This driver previously supported R-Car Gen4 S4/V4H/V4M. PCIe features of R-Car X5H PCIe4 are almost all the same, except for different PHY which has its own driver, slightly different initialization code and the DMA is no longer eDMA but HDMA. Endpoint mode is currently not implemented for R-Car Gen5 PCIe4.
