Hello everybody,

best wishes for new 2013 :-)

My question: are TI DM8168/DM8148 considered DaVinci processors ?

1. According to this page: yes
http://e2e.ti.com/support/dsp/davinci_digital_media_processors/default.aspx

2. According to these pages: no
http://processors.wiki.ti.com/index.php/DaVinci_PSP_Releases
http://processors.wiki.ti.com/index.php/DaVinci_GIT_Linux_Kernel

The DM8168 EVM board uses an obsolete 2.6.37-2.6.39 source
http://processors.wiki.ti.com/index.php/DM816x_AM389x_PSP_User_Guide

I would rather move to source tree at http://gitorious.org/linux-davinci

but I am not sure that it is the right one. Also, reinventing the
wheel/hot water is not interesting.

I think to work on DT support for DT8168/8148, and to submit the
patches to this mailing list.

Please correct me if I am wrong.

Hi Kiril and all,

I wish you an happy new year too.

I'm also interest about DM8168 support with the newest kernel. But I didn't
find any reference about this chip on linux-davinci 's git changelog ... I
am afraid that "no" work was done on the 3.x kernel branch.

So, like you, I'm looking for the right place to send my patches ;)

Best regards

The only mainline related work I know about is what Grant mentioned when
Matt posted his am33xx edma series:

http://lkml.indiana.edu/hypermail/linux/kernel/1210.1/02682.html

I've asked Grant about his changes, but he unfortunately hasn't had time
to post / clean them up yet.

AFAIK, DM814x is not completely ported to mainline kernel. Take a look at below

Thanks, but this was not my question.

Investigating further, your link above leads to
...
http://processors.wiki.ti.com/index.php/Category:EZSDK_Software_BOM

there is link to linux git repository
git://arago-project.org/git/projects/linux-omap3.git
http://arago-project.org/git/projects/?p=linux-omap3.git;a=summary

claiming:
"descripion: Linux PSP Integration/Staging Tree for ARM Cortex Based SoCs"
"owner: Sriram Govindarajan"
"last change: Wed, 12 Dec 2012 05:44:04 +0000"

and the linux tag is "04.04.00.01" for DM8168/8148 according to page
http://processors.wiki.ti.com/index.php/EZSDK_Feature_List

Going further:

http://arago-project.org/wiki/index.php/Main_Page
...
Arago Project is an open integration, build, and test infrastructure that
provides a portal into how Texas Instruments creates customer ready Linux SDKs.
Arago Project is an overlay for OpenEmbedded/Angstrom, which
targets TI platforms
OMAP3 (EVM and BeagleBoard) and DaVinci (6446, 355, 365, 6467...) and provides
a verified, tested and supported subset of packages, built with a free and
open toolchain (CodeSourcery Lite for now).

IRC channel: #arago

...

The arago git repository is frozen to 2.6.37.

So I see as option extracting some DM81xx parts from
arch/arm/mac-omap2 of Arago git repository,
and posting them to this mailing list.

... it gets funny ...

please check the up-right corner of the picture:

And "Reply to All" what have you read there.

The sad truth is that DM816x/814x SoCs share common IP blocks with
OMAPs and with DaVinci's

So the DM816x/814x source code was introduced in arch/arm/mach-omap2
