Subject: [-net-next v10 3/6] dt-bindings: net: snps,dwmac: Add 'ahb' reset/reset-name
Date: Mon, 3 Apr 2023 14:59:29 +0800	[thread overview]
Message-ID: <20230403065932.7187-4-samin.guo@starfivetech.com> (raw)
In-Reply-To: <20230403065932.7187-1-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.
