cdx: Fix off-by-one error in cdx_rpmsg_probe()

2025-08-28T14:31:09+00:00

commit 300a0cfe9f375b2843bcb331bcfa7503475ef5dd upstream. In cdx_rpmsg_probe(), strscpy() is incorrectly called with the length of the source string (excluding the NUL terminator) rather than the size of the destination buffer. This results in one character less being copied from 'cdx_rpmsg_id_table[0].name' to 'chinfo.name'. Use the destination buffer size instead to ensure the name is copied correctly.

cdx: Explicitly include correct DT includes

2023-08-04T14:21:20+00:00

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.

RPMsg is used as a transport communication channel. This change introduces RPMsg driver and integrates it with the CDX controller.
