Subject: Re: [PATCH v5 1/4] arm64: dts: lx2160a: describe the SerDes block #2

Hello everyone,

This is one of the patches in my series that hasn't received any 
feedback yet ...
(apart from Krzysztof correctly pointing out commit a description 
formatting mistake).

Please note that I intend on changing the new serdes_2 node to add 
status disabled by default.
Since the lynx-28g driver currently only supports network protocols,
enabling it by default could interfere with configurations using those 
SerDes's as PCI.
