From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx> Document the device tree bindings for the GBETH glue layer for the Renesas RZ/V2H(P) SoC, which integrates the `snps,dwmac-5.20` IP. The generic compatible string 'renesas,rzv2h-gbeth' is added, as this module is identical on both the RZ/V2H(P) and RZ/G3E SoCs.
