By the time you gave feedback, I have already sent the dtbo change for DTC to the device-tree-compiler list (based on Rob's suggestion). And it got merged today by David: https://github.com/dgibson/dtc/commit/163f0469bf2ed8b2fe5aa15bc796b93c70243ddc Can we please finalize what we need to do with naming here and be done with it, so I can rework my patches and get going ? Thanks. -- viresh
