2023-08-04cdx: Explicitly include correct DT includesRob Herring2-2/+4
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-03-29cdx: add cdx controllerNipun Gupta5-1/+373
CDX controller uses MCDI interface as a protocol to communicate with the RPU firmware and registers the detected CDX devices on the CDX bus. It also uses RPMsg as the communication channel with the Firmware.
