dpaa_eth: register a device link for the qman portal used

2019-10-31T19:13:34+00:00

Before this change, unbinding the QMan portals did not trigger a
corresponding unbinding of the dpaa_eth making use of it; the first
QMan portal related operation issued afterwards crashed the kernel.
The device link ensures the dpaa_eth dependency upon the qman portal
used is honoured at the QMan portal removal.

soc: fsl: qbman: allow registering a device link for the portal user

Introduce the API required to make sure that the devices that use
the QMan portal are unbound when the portal is unbound.

Merge branch 'pdf_fixes_v1' of https://git.linuxtv.org/mchehab/experimental into mauro

Bring in a set of post-thrashup fixes from Mauro.

docs: powerpc: convert docs to ReST and rename to *.rst

2019-07-17T09:57:51+00:00

Convert docs to ReST and add them to the arch-specific
book.

The conversion here was trivial, as almost every file there
was already using an elegant format close to ReST standard.

The changes were mostly to mark literal blocks and add a few
missing section title identifiers.

One note with regards to "--": on Sphinx, this can't be used
to identify a list, as it will format it badly. This can be
used, however, to identify a long hyphen - and "---" is an
even longer one.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

soc: fsl: qbman_portals: add APIs to retrieve the probing status

2019-05-20T19:28:16+00:00

Add a couple of new APIs to check the probing status of the required
cpu bound qman and bman portals:
 'int bman_portals_probed()' and 'int qman_portals_probed()'.
They return the following values.
 *  1 if qman/bman portals were all probed correctly
 *  0 if qman/bman portals were not yet probed
 * -1 if probing of qman/bman portals failed
Portals are considered successful probed if no error occurred during
the probing of any of the portals and if enough portals were probed
to have one available for each cpu.
The error handling paths were slightly rearranged in order to fit this
new functionality without being too intrusive.
Drivers that use qman/bman portal driver services are required to use
these APIs before calling any functions exported by these drivers or
otherwise they will crash the kernel.
First user will be the dpaa1 ethernet driver, coming in a subsequent
patch.

soc: fsl: dpio: Change bpid type to u16

2019-01-11T21:06:54+00:00

In all QBMan registers, the buffer pool id field is two bytes long.
The low level qbman APIs reflect this, but the high level DPIO ones
use u32. Modify them in order to avoid implicit downcasts.

soc: fsl: dpio: add a device_link at dpaa2_io_service_register

2019-01-11T21:06:54+00:00

Automatically add a device link between the actual device requesting the
dpaa2_io_service_register and the underlying dpaa2_io used. This link
will ensure that when a DPIO device, which is indirectly used by other
devices, is unbound any consumer devices will be also unbound from their
drivers.

For example, any DPNI, bound to the dpaa2-eth driver, which is using
DPIO devices will be unbound before its supplier device.

Also, add a new parameter to the dpaa2_io_service_[de]register functions
to specify the requesting device (ie the consumer).
