Not necessarily. of_platform_bus_probe() is an optional facility that is common used by SoCs that have lots of otherwise non-probable on chip devices, but for platforms with more classic setups, it's totally acceptable to have the platform code explicitely register only those devices it wants exposed.

Hello folks,
The following patch sequence is Emerson KatanaQp board support reworked after initial review/discussion.
The patches are incremental to minor mv64x60 code fixups sent by
Mark A. Greer on 11/08/07.
