Subject: [PATCH v6 3/8] dt-bindings: net: snps,dwmac: Add 'ahb' reset/reset-name
Date: Mon, 13 Mar 2023 11:46:40 +0800 [thread overview]
Message-ID: <20230313034645.5469-4-samin.guo@starfivetech.com> (raw)
In-Reply-To: <20230313034645.5469-1-samin.guo@starfivetech.com>
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.
