This will be required for the U-Boot env layout, see: [PATCH V3 4/6] nvmem: u-boot-env: convert to layout driver
On the other hand interpretation of match data is pretty much driver specific i see no reason for this to be in core.
Interpretation: yes. It's driver specific. Getting that struct however belongs to the core. We have all kind of helpers for getting driver private data. Those helpers live in some core code of subsystems.
