It shares the same driver family (RTL8367C) with other models as the RTL8365MB-VC. Its compatible string is "realtek,rtl8367s". It was tested only with MDIO interface (realtek-mdio), although it might work out-of-the-box with SMI interface (using realtek-smi). This patch was based on an unpublished patch from Alvin Šipraga .
