Subject: staging: fsl-mc: Move DPBP out of staging
Git-commit: 9c692d5ae7ea84d221d7504b7ebef07ea8f3ff27
Patch-mainline: v4.17-rc1
References: fate#326530,fate#326531,fate#326535,fate#326538,fate#326539
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
