From 64772e4d06a574e2359547d97f79674c28f07f75 Mon Sep 17 00:00:00 2001 From: Minda Chen Date: Wed, 27 May 2026 16:41:06 +0800 Subject: [PATCH] dt-bindings: net: starfive,jh7110-dwmac: Add jhb100 support The jhb100 GMAC still using Synopsys designware GMAC core. hardware features are similar with jh7100. Add jhb100 GMAC compatible and reset, interrupts features. jhb100 dwmac has only one reset signal and one interrupt line. jhb100 SGMII interface tx/rx mac clock is split and require to set clock rate in 10M/100M/1000M speed. So dts need to add a new rx clock in code, dts and dt binding doc.
