The following patch series add i2c support for omap5.
As well as enable I2C based devices like pressure and temperature
through device tree. Also add onchip keypad dts data.

Didn't we mentioned updating the trivial-devices.txt in the
documentation to list these devices?
Otherwise it it fine. You can add the documentation and I'll take these
patches as well along with the others.

I had posted a patch for updating the Documentation, though I created
a seperate
hwmon/tmp102.txt file. There is a comment to add it to trivial devices. So,
I will post a single patch doing so.

Cool, I'll take it on top of this one then.

Hi Sourav,
While rebasing your series on top of Tony's lo/devel-dt, I realized that the keypad nodes are not located at the correct place :-(
At the moment they are just floating at the top level of the dts while they belong to the ocp bus and thus should be put there.
I fixed that since it was trivial and cleaned as well the changelog and the comments to aligned then properly. I added as well the physical address to the node name and a label for easy reference at board level.
I did some basic test on my OMAP4 sdp, but that all I can do so far.
Could you just check if this is still fine for OMAP5 before I ask Tony to pull that.
I based that on top of Tony's DT patches due to conflict with the existing MMC patch in it.
The following changes since commit 85d7ff9b907685b6469058888f1d961b3e8d47ad:

My bad, never realised always used it at the top level. Sorry for the
inconvenience.

I just booted the below mentioned branch and its booting fine on omap5. Did
some keypad functionality test also and keypad seems to be working
fine on omap5.
