Thanks Dmitry and Florian.

Hi Dmitry,

I understand the dts changes are really needed for the touch screen
driver changes made in this patch. But currently there are no deployed
systems/customer's using this driver. So please pull the driver changes
and I will follow up to make sure dts changes also goes in.

Below is the latest patch set pushed.

Thanks ,
