Hi Tony and Rob,

Here is the updated version of the i2c + twl DT adaptation.

This update, compared to v1 [1], is mainly due to the merge into 3.2 of
Andy's i2c cleanup series that was introducing a lot of pdata accesses
at runtime.

The pm.c was updated to prevent the SR / VP initialization in the DT
context since none of them is DT aware for the moment.

A couple of basic i2c devices are added for panda, beagle and sdp board.

Patches are based on for_3.3/2_dt_irq, to get the latest GIC binding,
and are available here:
git://gitorious.org/omap-pm/linux.git for_3.3/3_omap_dt_i2c_twl

Tested on Beagle and sdp4430.

Comments are welcome.

Regards,
Benoit

In the case of DT, the PMIC and SR initialization will be done using
a completely different mechanism.

Disable this part if a DT blob is available.

Mmm, the send-email was aborted because Manju's email is not valid anymore.

I'll repost after removing the email from the patches.

Sorry for the noise.

Benoit
