Subject: [PATCH v5 8/8] [DNI] arm64: dts: renesas: eagle: Specify channel amplitude
Date:   Mon, 16 Nov 2020 14:53:05 +0100

Use the newly introduced 'maxim,initial-reverse-channel-mV'
property to specify the initial reverse channel amplitude when the
remote serializers are not pre-programmed with noise immunity threshold
enabled.
