+Subject: [PATCH 45/95] dt-bindings: net: snps,dwmac: Add 'ahb'
+ reset/reset-name
+
+According to:
+stmmac_platform.c: stmmac_probe_config_dt
+stmmac_main.c: stmmac_dvr_probe
+
+dwmac controller may require one (stmmaceth) or two (stmmaceth+ahb)
+reset signals, and the maxItems of resets/reset-names is going to be 2.
+
+The gmac of Starfive Jh7110 SOC must have two resets.
+it uses snps,dwmac-5.20 IP.
