[media] Kconfig: Re-enable Media controller support for DVB

2016-01-11T14:18:40+00:00

This was depending on broken because we're working at the
Media Controller API, with has... issues.

As this got fixed, we can re-enable it.

[media] use https://linuxtv.org for LinuxTV URLs

2015-12-04T12:38:59+00:00

While https was always supported on linuxtv.org, only in
Dec 3 2015 the website is using valid certificates.

As we're planning to drop pure http support on some
future, change all references at the media subsystem
to point to the https URL instead.

Merge tag 'media/v4.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

2015-06-26T00:55:48+00:00

Pull media updates from Mauro Carvalho Chehab:

 - Lots of improvements at the DVB API DocBook documentation.  Now, the
   frontend and the network APIs are fully in sync with the Kernel and
   looks more like the rest of the media documentation;

 - New frontend driver: cx24120

 - New driver for a PCI device: cobalt.  This driver is actually not
   sold in the market, but it is a good example of a multi-HDMI input
   device;

 - The dt3155 driver were promoted from staging;

 - The mantis driver got remote controller support;

 - New V4L2 driver for ST bdisp SoC chipsets;

 - Make sparse and smatch happier: several bugs were solved by fixing
   the issues reported by those static code analyzers.

 - Lots of new device additions, new features, improvements and cleanups
   at the existing drivers.

Kconfig: disable Media Controller for DVB

2015-06-18T06:53:36+00:00

Since when we start discussions about the usage Media Controller for
complex hardware, one thing become clear: the way it is, MC fails to
map anything different than capture/output/m2m video-only streaming.

The point is that MC has entities named as devnodes, but the only
devnode used (before the DVB patches) is MEDIA_ENT_T_DEVNODE_V4L.
Due to the way MC got implemented, however, this entity actually
doesn't represent the devnode, but the hardware I/O engine that
receives data via DMA.

By coincidence, such DMA is associated with the V4L device node
on webcam hardware, but this is not true even for other V4L2
devices. For example, on USB hardware, the DMA is done via the
USB controller. The data passes though a in-kernel filter that
strips off the URB headers. Other V4L2 devices like radio may not
even have DMA. When it have, the DMA is done via ALSA, and not
via the V4L devnode.

In other words, MC is broken as a whole, but tagging it as BROKEN
right now would do more harm than good.

So, instead, let's mark, for now, the DVB part as broken and
block all new changes to MC while we fix this mess, whith
we hopefully will do for the next Kernel version.

media controller: add EXPERIMENTAL to Kconfig option for DVB support

2015-05-08T17:48:49+00:00

The Media Controller DVB support is still an experimental feature,
as it is under heavy development. It is already said that it is
an experimental feature at the help, but let make it even clearer
and louder, as we may need to adjust some bits when we start using it
on embedded drivers.

[media] dvbdev: add support for media controller

2015-02-13T23:10:12+00:00

Provide a way to register media controller device nodes
at the DVB core.

Please notice that the dvbdev callers also require changes
for the devices to be registered via the media controller.

[media] bq/c-qcam, w9966, pms: move to staging in preparation for removal

2014-12-17T01:21:44+00:00

These drivers haven't been tested in a long, long time. The hardware is
ancient and hopelessly obsolete. These drivers also need to be converted
to newer media frameworks but due to the lack of hardware that's going
to be impossible. In addition, cheaper and vastly better hardware is
available today.

So these drivers are a prime candidate for removal. If someone is
interested in working on these drivers to prevent their removal, then
please contact the linux-media mailinglist.

Let's be honest, the age of parallel port webcams and ISA video capture
boards is really gone.

[media] Kconfig: do not select SPI bus on sub-driver auto-select

2014-09-04T15:18:49+00:00

We should not select SPI bus when sub-driver auto-select is
selected. That option is meant for auto-selecting all possible
ancillary drivers used for selected board driver. Ancillary
drivers should define needed dependencies itself.

I2C and I2C_MUX are still selected here for a reason described on
commit 347f7a3763601d7b466898d1f10080b7083ac4a3
