staging: fsl-mc: Add SPDX license identifiers

2018-01-22T10:45:21+00:00

The fsl-mc bus and dpio driver files use a combination of GPL-2.0 and
GPL-2.0+ OR BSD-3-Clause licenses. Add SPDX tags and delete the full
license text, keeping the existing license for each file. Add GPL-2.0
for Kconfig / Makefile, where not present.

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.

staging: fsl-mc: use 32bits to support 64K size mc-portals

2017-11-28T12:58:31+00:00

As per APIs each mc-portal is of 64K size while currently
16bits (type u16) is used to store size of mc-portal.
In these cases upper bit of portal size gets truncated.

staging: fsl-mc: add support for device type

2017-11-27T08:20:41+00:00

The MC bus has different types of devices and this is supported by
device model. This patch adds initial support for device types
(defines them, adds helpers and sets the device type).

staging: fsl-mc/dpio: remove couple of unused functions

2017-11-27T08:20:41+00:00

These couple of functions are not yet used so lets remove them
for now and add them back when/if needed.

2017-11-27T08:20:40+00:00

Couple of API functions are not used so lets drop them together with
the associated structures and defines.

staging: fsl-mc/dpio: Fix incorrect comparison

2017-10-03T16:34:56+00:00

For some dpio functions, a cpu id parameter value of -1 is
valid and means "any". But when trying to validate this param
value against an upper limit, in this case num_possible_cpus(),
we risk obtaining the wrong result due to an implicit cast.

Avoid an incorrect check result by explicitly comparing the
cpu id with the "any" value before verifying the upper bound.

staging: fsl-mc: include irqreturn.h as needed

2017-07-30T15:25:04+00:00

The recent reshuffling of header files left one type definition
missing in some configurations:

In file included from drivers/staging/fsl-dpaa2/ethernet/dpaa2-eth.h:39:0,
                 from drivers/staging/fsl-dpaa2/ethernet/dpaa2-ethtool.c:34:
drivers/staging/fsl-dpaa2/ethernet/../../fsl-mc/include/dpaa2-io.h:86:1: error: unknown type name 'irqreturn_t'; did you mean 'irq_count'?
 irqreturn_t dpaa2_io_irq(struct dpaa2_io *obj);

I have not bisected this to the exact patch that introduced the problem,
but the solution is obvious, we just need to include the header that
contains the type.

staging: fsl-mc: make dprc.h header private

2017-06-29T14:38:53+00:00

dprc.h is only used in the mc bus driver so move it together with the
sources thus making it private.

staging: fsl-mc: move mc-cmd.h contents in the public header

2017-06-29T14:38:53+00:00

mc-cmd.h contains some low level functions used to encode and decode
commands to the MC. They are used by the drivers so move them to the
public headers and get rid of the mc-cmd.h header.
