All the training you need is here: http://free-electrons.com/docs/ The training material is up to date and includes DeviceTree material. Another good reference are Linux books by Robert Love, namely "Linux Kernel Development" and "Linux System Programming². I like selected these because they are much more current than "Linux Device Drivers 3rd edition² but the updated version is due in July 2014.
