media: entity: Pass entity to get_fwnode_pad operation

2020-05-18T09:12:05+00:00

Add a missing pointer to the entity in the media_entity operation
get_fwnode_pad. There are no implementers of this op yet, but a future
entity that does so will almost certainly need a reference to itself
to carry out the work.

media: mc/Kconfig: remove staging dependency for request API

2020-04-17T06:57:39+00:00

When the request API got merged, only drivers at staging were
using it. As we wanted to be able to do future changes on it,
we added an artificial depends on STAGING_MEDIA.

Yet, request API is there for quite some time now, and
didn't suffer any API breakages during this time. So, drop
this.

media: Kconfig: Don't expose the Request API option

2020-04-16T08:36:11+00:00

The Request API isn't meant to be chosen by users,
but instead should be selected by drivers that want
to support it.

Hantro and Cedrus are already selecting the right options,
so only the test drivers need to be fixed.

media: Kconfig: move media controller core select to main Kconfig

2020-04-14T08:29:06+00:00

Let's place the main API selections at the media/Kconfig file,
as this way we can better organize things.

media: Kconfig files: use select for V4L2 subdevs and MC

2020-04-14T08:29:05+00:00

There are lots of drivers that only work when the media controller
and/or the V4L2 subdev APIs are present.

Right now, someone need to first enable those APIs before
using those drivers.

Well, ideally, drivers, should, instead *optionally*
depend on it, in order for PC camera drivers to be able to use
them, but nowadays most drivers are UVC cameras, with don't
require a sensor driver.

So, be it.

Let's instead make them select the MEDIA_CONTROLLER and the
SUBDEV API, in order to make easier for people to be able
of enabling them.

media: add SPDX headers on Kconfig and Makefile files

2020-04-14T08:29:05+00:00

Most of media Kconfig/Makefile files already has SPDX,
but there are a few ones still missing. Add it to them.

media: mc-entity.c: use WARN_ON, validate link pads

2020-02-24T16:21:58+00:00

Use WARN_ON instead of BUG_ON.

Add two new WARN_ONs to verify that the source pad is really a source
and that the sink pad is really a sink.

media: mc-entity.c: use & to check pad flags, not ==

2020-02-24T14:10:04+00:00

These are bits so to test if a pad is a sink you use & but not ==.

It looks like the only reason this hasn't caused problems before is that
media_get_pad_index() is currently only used with pads that do not set the
MEDIA_PAD_FL_MUST_CONNECT flag. So a pad really had only the SINK or SOURCE
flag set and nothing else.

Merge tag 'v5.2-rc4' into media/master

2019-06-11T16:09:28+00:00

There are some conflicts due to SPDX changes. We also have more
patches being merged via media tree touching them.

So, let's merge back from upstream and address those.
