[RFC] [Maverick] Pull ti-omap4 branch

[Jan, Sebastien]

Hi Amit,

I agree with you and I shall have developed more my answer:
we plan to have an intermediate re-base on a .35-rc kernel, as you suggest.
We shall have this update available beginning of August.

Regards,
Sebastien

Sebastien,

We should _not_ wait for 2.6.35 to be released to get the first patch drop
into Ubuntu.

2.6.35 is already at -rc3, so there is unlikely to be any core API changes in
the kernel. The patches going into the plat-omap and mach-omap will also be
down to a few bugfixes.

So, IMHO, TI should rebase on top of -rc3 or -rc4 and get this into Ubuntu.
There after, it will be a lot easier rebasing it to the point when 2.6.35 is
final.

Regards,
Amit
