From c639a708a0b8b69b7d580292a8f0405124488bad Mon Sep 17 00:00:00 2001 From: Pranavi Somisetty Date: Thu, 24 Aug 2023 17:14:56 +0530 Subject: [PATCH] dt-bindings: net: xilinx_gmii2rgmii: Convert to json schema Convert the Xilinx GMII to RGMII Converter device tree binding documentation to json schema. This converter is usually used as gem <---> gmii2rgmii <---> external phy and, it's phy-handle should point to the phandle of the external phy.
