As i didn't know how to trigger dynamic loading from userspace i also applied the following patch: OF: DT-Overlay configfs interface https://github.com/raspberrypi/linux/commit/8f1079750ce2fce4c4c2b4f8759ea57c8fb167d3 Now i got the loading of the devicetree overlay working :-)... but only if i enable OF_UNITTEST. I find this a little strange especially as it slows boot time. I also tried adding: select OF_DYNAMIC to my OF_CONFIGFS patch but this didn't help. Also patching away "if OF_UNITTEST" config OF_DYNAMIC - bool "Support for dynamic device trees" if OF_UNITTEST + bool "Support for dynamic device trees" didn't help? Besides these nitpicks i am really happy to see this in mainline as it really makes working with dynamic fpga based hardware much cleaner!
