+Note that struct mmc_platdata is defined in the C file, not in a header. This +is to avoid needing to include dt-structs.h in a header file. The idea is to +keep the use of each of-platdata struct to the smallest possible code area. +There is just one driver C file for each struct, that can convert from the +of-platdata struct to the standard one used by the driver. + In the case where SPL_OF_PLATDATA is enabled, platdata_auto_alloc_size is still used to allocate space for the platform data. This is different from the normal behaviour and is triggered by the use of of-platdata (strictly
