Cleanup Samsung stuff

Cleanup Samsung stuff

[Kukjin Kim]

Hi all,

I think, you know about current situation of Linux ARM world.

So...

As Russell suggested, I also will focus on consolidations and bug fixes for
Samsung stuff for a while so don't complain about missing new stuff. In my
opinion, we can keep going it later...

As a note, I'm doing(or preparing) following at the moment.

- Removing some "mach-s5pxxxx"s
- Removing useless header files in include/{mach,plat} of Samsung
- Samsung GPIO stuff cleanup/consolidation
- Samsung DMA stuff consolidation?
- Device tree (with Linaro)
- and so on...

If required anything else, please let me know.

Thanks.

Best regards,
Kgene.

Why not mach-s3c series? don't you think too much plat-{s3c, s5p,
samsung}? how about to use the plat-samsung only?

   - Strange Samsung Clock and names consolidation.
   - IRQ stuff (some parts are done by tglx but need to use the
generic IRQ base instead of odd +32 magic)
   - generic IOMMU consolidation.

BTW, who works on this at LSI?

Thank you,

Hello everyone,

Anyway, I've got a quick question about the directory structure in arch/arm/*

Is there any reason not to keep mach-* in plat-* directories while
mach-* appears to be a "sub-categories" of plat-*?

For example, rather than the current structure:
arch/arm/plat-samsung/
arch/arm/mach-s5pv210/
arch/arm/mach-s5p****/
, why don't we structure them like:
arch/arm/plat-samsung/mach-s5pv210/
arch/arm/plat-samsung/mach-s5p****/

For mach-* that is not included in and does not use any plat-*, we may
make "arch/arm/plat-common" or just put them at arch/arm/.

Probably there could be discussions like this (likely), but I just
don't know why we are not structured like that. If it is because we
have some mach-* that use multiple plat-*, (multiple inheritance?) we
may be able to move on with this consolidation.



Cheers!

What is going on with device tree?  I've asked a couple of times about
this in the other thread but I'm still not clear where the code is or
what could usefully be done with it.

The initial work on Samsung's s5pv310 is available at
http://lists.ozlabs.org/pipermail/devicetree-discuss/2011-February/004350.html

It is based on Grant's tree.
git://git.secretlab.ca/git/linux-2.6 devicetree/test

Currently I am working on supporting clkdev and Jeremy's common clock
for all of Samsung's platforms and then continue with the device tree
support for s5pv310.

Regards,
Thomas.

I already posted some patches that add DeviceTree to s3c24xx (gpio, sdi).
I'm hanging on sdi because I found that mmc-spi already has some DT
support and I'm working to generalize it.

If nobody opposes I'll continue with the effort.

cheers,
Domenico

Greetings All,


i've been looking at a number of machine files for boards that are no
longer in production(mainly the ones i maintain), thoughts on removing them?

Are you planning to remove mach-s5pc100? If yes, is this with the 
intention of reducing arch/arm code size (by merging, say, with the 
s5pc110 tree), or because of some upcoming Samsung EOL event? :-(

(I'm building security cameras based on the s5pc100, working with 
mach-s5pc100 issues every day).

Best regards, ....Nick Pelling....

Hmm...There is no decisions about that yet. Just I'm thinking and checking
the status of each ARCH(mach-xxxx).
Of course, if any updates, will inform here.

Only for S5PC100?

Thanks.

You mean mach-amlm5900.c and mach-tct_hammer.c in mach-s3c2410?

Hmm...as you know, we need to think again and talk to others before removing
them even though you made them and as I said in previous reply, there is no
decisions yet about that.

As a note, Ben Dooks maintains S3C SoCs. I mean I need to talk to him about
that in detail.

Thanks.

Kgene.

Could you please send them to me and Ben Dooks?

Hi Thomas,

Thanks for your reply.

I also will review your patches of device tree and supporting clkdev soon.

If any updates after your posting, please let me know :)

Kgene.
