[PATCH 01/11] PCI: dwc: Add Renesas to the RAS DES VSEC list

From: Koichiro Den

Date: Thu Sep 17 2026 - 23:21:36 EST


The Root Port on R-Car Gen4 (DWC 5.20a) carries the RAS DES capability
with the stock DesignWare VSEC ID (0x02, rev 4), but vendor ID 0x1912 is
not in dwc_pcie_rasdes_vsec_ids[]. Add Renesas to the list.
