Subject: [PATCH] arm64: dts: nitrogen8-som: correct network PHY reset
Date: Sat, 11 Dec 2021 23:17:43 +0100	[thread overview]
Message-ID: <20211211221743.1665873-1-dev@lynxeye.de> (raw)

Add the missing reset-gpios property to allow Linux to fully reset
the network PHY and fix the pinmux to add the neccessary pull-ups
for the PHY strap configuration.
