No device tree support. There is no any "dtb" files under the "/boot" partition and "/proc/device-tree" doesn't exist either.

@Usman, I left Linaro Android team & joined in Linaro QA service team at April 2012, working for the Quality Assurance service. I didn't follow the Device Tree topic for a long time since this task was transferred to the landing team & Linaro kernel team at October 2011. Therefore, I'm afraid that I can't provide information about how to enable this feature.

Would you please contact the Linaro Samsung Landing team & Linaro kernel team for more information? You can find their contact information on these links:

Linaro Samsung Landing Team: http://www.linaro.org/about/meet-the-team/samsung-landing-team

Linaro Kernel Team: http://www.linaro.org/about/meet-the-team/kernel

Also, you may can contact Linaro Android team for the information about Device Tree on Linaro Android image:

Thank you.
