Subject: [linux-next-v1 3/3] arm64: dts: rockchip: Fix ethernet reset node Rock 3A sbc
Date: Fri, 11 Nov 2022 09:42:35 +0000	[thread overview]
Message-ID: <20221111094238.1640-3-linux.amoon@gmail.com> (raw)
In-Reply-To: <20221111094238.1640-1-linux.amoon@gmail.com>

Add support for snps,reset-gpio reset ethernet gpio pins and
drop the mdio reset code.
