drivers/staging/fsl-mc: Use devm_memremap/devm_ioremap for DPIO

2018-04-23T13:51:34+00:00

Change the mapping of the QBMan cache enabled area from using ioremap_wc()
to devm_memremap(). This allows the __iomem attribute to be removed from
the pointer (which makes sense as accesses treat this as cacheable memory
not IO memory).  These changes allow sparse checks to pass.

Also use devm_ioremap() for the cache inhibited area so unmap occurs
automatically when the device is released.

staging: fsl-mc: Move DPCON out of staging

2018-03-14T12:18:42+00:00

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

staging: fsl-mc/dpio: Add dpaa2_io_service_select() API

2018-01-08T15:47:23+00:00

All DPIO service API functions receive a dpaa2_io service pointer
as parameter (NULL meaning any service will do) which indicates
the hardware resource to be used to execute the specified command.

There isn't however any available API for obtaining such a service
reference that could be used further, effectively forcing the users
to always request a random service for DPIO operations.
(The DPIO driver holds internally an array mapping services to cpus,
and affine services can be indirectly requested by a couple of API
functions: dpaa2_io_service_register and dpaa2_io_service_rearm
use the cpu id provided by the user to select the corresponding
service)

This patch adds a function for selecting a DPIO service based on
the specified cpu id. If the user provides a "don't care" value
for the cpu, we revert to the default behavior and return the next
DPIO, taken in a round-robin fashion from a list of available
services.
