There is Yosemite4 board already supported. What is this for?

Yosemite4 is a server chassis which is managed by a BMC.  The BMC is on
a pluggable module card.  Typically we've used Aspeed chips for this,
but we are building an alternative BMC module using Nuvoton BMC chips.

We will end up with two different BMC chips / images that could be
managing the same server hardware.  Since the Aspeed and Nuvoton chips
are different there are unfortunately 2 device trees (one for each chip).

Please let us know if there is a better way to document this.

There are few ways to solve this, like having different compatibles or
having some shared compatibles to note common part of hardware. However
usually the final compatible represents the final device, which here you
use for two entirely different products. This works only for the cases
of carrier boards, where that compatible indeed represents the same
hardware.

Not your case. This needs fixing.

Krzysztof

This patch:
+	model = "Facebook Yosemite 4 BMC";
+	compatible = "facebook,yosemite4-n-bmc", "nuvoton,npcm845";

Aspeed patch:
+       model = "Facebook Yosemite 4 BMC";
+       compatible = "facebook,yosemite4-bmc", "aspeed,ast2600";

These have different compatibles already ('-n' for Nuvoton).  Do we just
need the model to be clearly different also?  Maybe there is something
else I'm not understanding.

Ah, no, it's fine. It is just a bit confusing.

However commit msg for sure misses a lot of this explanation. Please
write something useful to avoid such discussions...

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:

Please base on ongoing work adding specific compatibles.

reg is always after compatible.

Eh... so again you make the same mistakes and send the same downstream
poor code with the same bad patterns we asked to fix.

compatible is always first, reg is second. Why do you need this property
anyway?
