The file ddk750_help.c contained only one function declaration, so it was merged into ddk750_chip.c to simplify the driver. Also, ddk750_help.h was merged into ddk750_chip.h to keep consistency. With these changes a few global variables are removed and the function ddk750_set_mmio is rewritten, so its purpose in the code is clearer.
