Hi all,

There were some murmurings on IRC last week about renaming the of_*()
routines.

...

quoted

The thinking is that on many platforms that use the of_() routines
OpenFirmware is not involved at all, this is true even on many powerpc
platforms. Also for folks who don't know the OpenFirmware connection
it reads as "of", as in "a can of worms".

So I'm hoping people with either say "YES this is a great idea", or "NO
this is stupid".

I'm still hoping, but so far it seems most people have got better things
to do, and of those that do have an opinion the balance is slightly
positive.

I assume you'll be also publishing the script that you use for
generating the massive patch.  I expect that there will be a few
iterations of running the rename script to convert over all the
stragglers.

Yep sure, I'll just make it less crap first.

It should also be negotiated with Linus about when this
patch should get applied.  I do NOT want to cause massive merge pain
during the merge window.

Obviously.

Andrew/Linus: Before Michael proceeds too far with this rename, are
you okay with a mass rename of the device tree functions from of_* to
dt_*?  Nobody likes the ambiguous 'of_' prefix ("of?  of what?"), but
to fix it means large cross-tree patches and potential merge
conflicts.

It'd also be good to hear from DaveM, sparc is the platform with the
strongest link to real OF AFAIK, so the of_() names make more sense
there.

One Laptop Per Child ships real Open Firmware on its x86 Linux systems, 
of which approximately 2 million have been shipped or ordered.  An ARM 
version, also with OFW, is in the works.

OK. I don't see any code under arch/x86 or arch/arm that uses of_()
routines though? Or is it under drivers or something?

That said, I don't particularly like the abbreviation "of" either; I 
abbreviate Open Firmware as "OFW".

I don't mind using "dt_" to apply to device tree things; I think it's 
clearer than "of_".   Ideally, it would be nice to acknowledge the 
historical connection in some way, but confusing nomenclature probably 
is not the way to go about it.

Cool. I think there will still be a few things that have OF in the name,
at least for a while, and I'm sure the doco will still mention OF, so I
don't think the connection will be lost.

cheers
