[PATCH v2 2/2] ARM: dts: aspeed: add device tree for YADRO VEGMAN BMC

[Andrei Kartashev]

YADRO VEGMAN is x86 based servers family with ASPEED AST2500-based BMC.
Currently there are three models:
* VEGMAN N110
* VEGMAN S220/320
* VEGMAN R120/220

The dts files provides configuration for BMC system.

Can we utilize https://github.com/openbmc/docs/blob/master/designs/device-tree-gpio-naming.md to get some consistent naming across the GPIO’s on OpenBMC machines?

Some names here are standard for Intel daemons like x86-power-control,
host-error-monitor, pfr-manager, IntrusionSensor and so on. Other lines
just called same as in schematics to make it easy for our engineers to
understand what does it refer to. BTW, most of the lines there not used
by software and appeared just because dts files are supposed to be
hardware description and thus we describe all we have in schematics.

We can rename all this according to guide you mention, but are you
sure, there is any sense to do so?
Keep in mind, currently there are lot of dts files which also don't
follow convention, so I believe, it is unnecessary work.

Gently ping.

Is there any other comments for dts files?

I have a strong preference for using the naming document. It provides
consistency, which makes it easier to review. I'm encouraging that for
any new dts.

If you think it makes the descriptions less useful for your platform
then that's a reasonable reason to not follow the convention.

Cheers,

Joel

Actually, what I would prefer is that these well established signal
names that appear in the x86 industry servers be enumerated in the
gpio naming document and be accepted like the original OpenPOWER
legacy names were.   This will clearly show the names that appear 
on other systems and will help reviewing things like power control 
applications.

Andrei does this sound reasonable?

Actually, as TOF member I can't decline this input, it really sounds
reasonable and important for OBMC in common. I will take this action,
but this will require some time since now I'm working on other tasks.
