True. However, there are currently drivers which need platform data for its initialisation (like drivers/gpio/pca953x.c). Unless these drivers are rewritten, they can't be loaded just by parsing the device tree, so they must be loaded from platform init code and here the adapter index is needed to attach the driver.
