One dtc feature that is still missing is what Pantelis calls "syntatic sugar".
His patch for that has not yet been accepted into the dtc project if I have
been following along correctly.

Without the syntactic sugar, the source .dts has to expose the details
of the fragment and __overlay__ nodes.

Hi,

    This mail is regarding the DT overlay support in the Linux 
kernel
    I am able to make the device-tree overlay work out of box by 
using my own dtc complier (I mean I used the dtc compiler
    Available here 
http://www.embedded-things.com/bbb/patching-the-device-tree-compiler-for-ubuntu/
  )
    When can I expect the same changes in the scripts/dtc in 
mainline 
    In case of any support needed for testing I can help on testing 
the same I works in Xilinx and we had a lot of combinations to test overlay ☺ 

    

Regards,
Navakishore.
