There's a decade plus old comment in of_device.h: #include /* temporary until merge */ Who's this Grant person that wrote this? ;) It gets better. of_device.h also pulls in of.h, and of_platform.h includes of_device.h. So naturally, drivers include all combinations of those 3 headers and sometimes they actually need them. I started on fixing this years ago, but just dropping the circular includes and fixing all the fallout was massive and didn't sit well. Pulling in of_device.h in all the drivers that happen to call only of_device_get_match_data/of_match_device didn't seem great when the rest of of_device.h would never be needed. of_device.h being everything that works on a struct device is not a great split because several types of users deal with struct device. The better split seems to be by user (subsys driver vs. consumer) which several subsystems now do. For of_device.h, the users can primarily be split between bus implementations and device drivers. Device drivers also typically need of.h to read properties. So let's move of_device.h towards just bus related functions and move device driver related functions to of.h. This series is just the first step. It makes a couple of clean-ups to replace some includes with forward declarations. It moves of_device_get_match_data() and of_cpu_device_node_get() to of.h. The former move is transparent for now and preparation for the next series. The last part of the series updates drivers using of_cpu_device_node_get() and/or relying on the implicit cpu.h include which is removed in the last patch.
