[v2] arm64: allwinner: a64: add device tree for SoPine with clusterboard

  Hello Krzysztof,

Thank you for your feedback! I've fixed the indentation and I've added 
the compatible and model elements.

Greetings,
Renze Nicolai


The Pine64 clusterboard needs a to have the tx delay changed to
500ps for ethernet to work. This solution was described by multiple
people on the Pine64 forum years ago and nobody has submitted it.

Add a device tree for SoPine with the clusterboard.

You didn't document compatible in bindings as instructed by Krzysztof. That 
should be in a patch preceding this one.

Comments like this, which are not part of commit message, should be either in 
cover letter or right below --- line, so they are ignored when patch is 
applied. While above comment can be considered as changelog of sort, it's 
preferred to write it as list, point by point, in area which is ignored when 
applying patch.

I guess you don't use "git send-email" to send your patches? New versions 
should not be send in reply to old ones.

When you're adding new board, commit message should describe new board either 
by stating features or telling which board is similar and what are the 
differences. Something like that clusterboard is almost the same as baseboard 
except ethernet TX delay, which is 500 ps. Omit second part of second 
statement, it's not relevant.

Best regards,
Jernej

One small issue, I think the clusterboard has one node that comes with
eMMC, which is different from other nodes.

Should these have different DT's ?
