[PATCH 0/3] [RFC] enable Pegasus touch screen

[edwin.zhai]

From: Zhai Edwin <edwin.zhai@intel.com>

Tom,
These changes, based on meta-intel/tzanussi/pegasus, are needed to enable
eGalax touch screen on Pegasus. Could you pls. help to review?

When will you push Pegasus changes into meta-intel/master? We can have a common
place for people to try pegasus...

Thanks,
Edwin

Hi Edwin,

First, I don't think this is the correct list for meta-intel stuff,
please use the yocto list.

Anyway, the first two patches look ok to me, but the 3rd seems to be a
combination of what it says in the title, enabling touch screen kernel
config, and updating the BSP to work with the current kernel recipes.
The latter should I think be squashed into the base BSP, which isn't
posted.

The meta-pegasus you pointed to seems to be an old version, basically
the same prototype version I gave you for the demo.  I thought the
current one had been updated to address the comments from the quick
review of Aug 9:

- meta-pegasus - commented-out stuff in pegasus.conf, xorg.conf,
linux-yocto-2.6.37.bbappend, ReleaseNotes are unrelated to the BSP, etc.

Also, it has a blacksand.pdf and has old kernel recipes, etc.

Basically, it needs to be cleaned up a bit before it can be pulled in,
and should be buildable without relying on later patches.

Also, I'm wondering if there's a reason it's using 2.6.37 - we're at 3.0
now, and it would be good if it used that.

Finally, please also add yourself or whoever will be the maintainer
going forward to meta-intel/MAINTAINERS...

Thanks,

Tom

Do you mean we need rebased against branch of 
meta-intel/tzanussi/pegasus-v2?

Have we tested 3.0 on Pegasus or N450 system? I remember your mentioned 
graphic crash with linux 3.0...

I don't know - I would think you'd just clean up whatever version you've
been using...

The n450 BSP has been moved to 3.0, but I haven't worked on pegasus
since the initial prototype, so I don't know if it's been tested on 3.0.
I do recall running into problems with graphics, but don't remember the
details...
