Hi Bjorn,

From Documentation/driver-api/driver-model/platform.rst:
"Platform devices are devices that typically appear as autonomous
entities in the system. This includes legacy port-based devices and
host bridges to peripheral buses, and most controllers integrated
into system-on-chip platforms. What they usually have in common
is direct addressing from a CPU bus. Rarely, a platform_device will
be connected through a segment of some other kind of bus; but its
registers will still be directly addressable."

Do you agree that the above description is not a good match for the
ufs-bsg kernel module?
