[PATCH v5 8/8] [DNI] arm64: dts: renesas: eagle: Specify channel amplitude

From: Jacopo Mondi
Date: Mon Nov 16 2020 - 08:54:01 EST


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.
