Move the source files out of staging into their final locations:
- dpbp.c goes to drivers/bus/fsl-mc/, next to the core infrastructure
- dpbp-cmd.h gets merged into drivers/bus/fsl-mc/fsl-mc-private.h, next
to the other internally used APIs
- dpbp.h gets merged into include/linux/fsl/mc.h, exposing the public
API
Update references in the dpaa2-eth staging driver.
DPBP stands for Data Path Buffer Pool - you can read more about the
object in Documentation/networking/dpaa2/overview.rst

Move the source files out of staging into their final locations:
- dpcon.c goes to drivers/bus/fsl-mc/, next to the core infrastructure
- dpcon-cmd.h gets merged into drivers/bus/fsl-mc/fsl-mc-private.h, next
to the other internally used APIs
- dpcon.h gets merged into include/linux/fsl/mc.h, exposing the public
API
Update references in the dpaa2-eth staging driver.
DPCON stands for Data Path Concentrator - an interface between DPIO
(Data Path IO) and its users (e.g. dpaa2-eth). You can read more about
DPIO in Documentation/networking/dpaa2/overview.rst
