The binding document is deliberately using "renesas,rcar-gen5-pcie4" DT compatible string to discern R-Car X5H PCIe4 controller supported by this binding, from R-Car X5H PCIe6 controller which will use a separate binding. The R-Car X5H PCIe4 controller does no longer include PHY register range, the PHY is now a separate IP and referenced via the 'phy' DT property. The 'reg' and 'reg-names' DT properties therefore differ between R-Car Gen4 PCIe and R-Car X5H PCIe4, and the difference is handled in the allOf section.
