#1470793 — [PATCH v8 15/18] ARM: STi: DT: STiH407: Add uniperif reader dt nodes

This patch adds the DT node for the uniperif reader
IP block found on STiH407 family silicon.

I find it's normally nicer to place the status of the node at the
bottom, separated by a '\n'.  There isn't a functional difference
admittedly, but it would be my preference, since it's not describing
the device per se.

We usually use lower-case for the address.

Since this has a 'reg' property, the '0' in the node name does not
look appropriate.

Oooo, not seen something like this before.

If it does not already have one, it would require a DT Ack.

> +			st,version = <3>;

This will likely need a DT Ack too.  We usually encode this sort of
information in the compatible string.

Hi Lee,

Thanks for reviewing and your very valuable feedback.

Ok I'll add a superflous '\n' in the next version.

Will change to your preference in the next version.

No idea, the driver got merged 1 year ago.

Arnaud did you get a DT ack when you merged this driver & binding?

Everyone loves a smart arse!

In this case I believe the '\n' to be a functional separator and not
superfluous at all.

Well Rob's the boss.  We certainly never used to take 'device ID' or
'version' attributes.  I guess something must have changed.

This field could be suppressed and handled in source code, using
st,uniperiph-id to retreive it.

I will try to provide patches for code and bindings rework this week.

That would be better.

I'm surprised Mark didn't notice this.

He's usually pretty good at picking stuff like that up.
