Mauro Carvalho Chehab 9958d30f38 media: Kconfig: cleanup VIDEO_DEV dependencies
media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.

On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
	1) enable Video4Linux and make its Kconfig options to appear;
	2) it makes the Kernel build the V4L core.

while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.

With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.

At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:

	menu "Video4Linux options"
		visible if VIDEO_DEV

	source "drivers/media/v4l2-core/Kconfig"
	endmenu

but it doesn't affect anymore the V4L core drivers.

The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:

	config VIDEO_V4L2
		tristate
		depends on (I2C || I2C=n) && VIDEO_DEV
		select RATIONAL
		select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
		default (I2C || I2C=n) && VIDEO_DEV

In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.

Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

Mauro Carvalho Chehab d7700ca98d media: platform: Kconfig: place platform drivers on a submenu
Just like media bus drivers, place platform drivers on a
submenu, in order to better organize user-selection:

    Media drivers  --->
	    *** media drivers ***
	[*] Media USB Adapters  --->
	[*] Media PCI Adapters  --->
	-*- Radio Adapters  --->
	[*] Media platform devices  --->
	    *** MMC/SDIO DVB adapters ***
	< > Siano SMS1xxx based MDTV via SDIO interface
	[*] V4L test drivers  --->
	[*] DVB test drivers  --->
	    *** FireWire (IEEE 1394) Adapters ***
	<*> FireDTV and FloppyDTV
	    *** common driver options ***
	[ ] Enable Remote Controller support for Siano devices
	[ ] Enable debugfs for smsdvb

As this submenu depends on MEDIA_PLATFORM_DRIVERS and defaults to "y",
there's no need to change already-existing .config entries, nor touch
the several make *_defconfig.

There are some long-time mistakes related to build test
drivers, with regards to depends on/select. Also, as we
now want to build any test driver without needing to
enable anything else, change the logic in order to properly
filter them.

Please notice that the PCI skeleton is somewhat an
exception, as it requires to select *both* SAMPLES and
MEDIA_TEST_SUPPORT. I almost changed it to be either one,
but decided to keep it as-is, as this is something that
we don't really need to be included on any distribution.

Mauro Carvalho Chehab a3b91d8bd1 media: Kconfig: better support hybrid TV devices
Right now, if one has an hybrid TV card, it has to select
both analog and digital TV support, as otherwise the needed
core support won't be selected.

Change the logic to auto-select the core support for those
drivers, as this is a way more intuitive.

It should be noticed that, as now both DVB_CORE and VIDEO_DEV
defaults depends on selecting a hybrid cards, we had to remove
the explicit dependencies there, in order to avoid circular
dependencies.

That requires some tricks:

1) the prompt should not be not visible when an hybrid card
   is selected, as the user shold not change it.

2) When a media hybrid device is selected, the modular
   option for DVB_CORE and VIDEO_DEV will follow the
   MEDIA_SUPPORT dependency, as we can't have a core
   built with "y" with a driver built as module.

Note: while here, moved two pure V4L2 PCI drivers out of the
"hybrid" part of config and consider pvrusb2 as an hybrid
device.

When the first test device was added (vivi.c), there were just
one file. I was too lazy on that time to create a separate
directory just for it, so I kept it together with platform.

Now, we have vivid, vicodec, vim2m and vimc. Also, a new
virtual driver has been prepared to support DVB API.

So, it is time to solve this mess, by placing test stuff
on a separate directory.

It should be noticed that we also have some skeleton drivers
(for V4L and for DVB). For now, we'll keep them separate,
as they're not really test drivers, but instead, just
examples. The DVB frontend ones will likely be part of a new DVB
test driver. By that time, it should make sense to move them
here as well.

Some users have been having a hard time finding the hidden
menus. A typically case are camera sensor drivers
(e.g IMX219, OV5645, etc), which are common on embedded
platforms and not really "ancillary" devices.

The problem with MEDIA_SUBDRV_AUTOSELECT seems to be related
to the fact that it uses the "visible" syntax to hide
the menus.

This is not obvious and it normally takes some time to
figure out.

To fix the problem, add a comment on each of hidden menus,
which should clarify what option is causing menus to be hidden.

Bartlomiej Zolnierkiewicz 2f39cce963 media: remove redundant 'default n' from Kconfig-s
'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.

Also since commit f467c5640c ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:

    ...
    One side effect of (and the main motivation for) this change is making
    the following two definitions behave exactly the same:

        config FOO
                bool

        config FOO
                bool
                default n

    With this change, neither of these will generate a
    '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
    That might make it clearer to people that a bare 'default n' is
    redundant.
    ...

Mauro Carvalho Chehab b60a5b8dcf media: Kconfig files: use the right help coding style
Checkpatch wants to use 'help' instead of '---help---':

	WARNING: prefer 'help' over '---help---' for new help texts

Let's change it globally at the media subsystem, as otherwise people
would keep using the old way.

Sakari Ailus 078ab3ea2c media: Add a Kconfig option for the Request API
The Request API is now merged to the kernel but the confidence on the
stability of that API is not great, especially regarding the interaction
with V4L2.

Add a Kconfig option for the API, with a scary-looking warning.

The patch itself disables request creation as well as does not advertise
them as buffer flags. The driver requiring requests (cedrus) now depends
on the Kconfig option as well.

This adds a 'select' statement for it, plus a dependency that
ensures that videobuf2 in turn works, as it in turn depends on
VIDEO_V4L2 to link, and that must not be a module if videobuf2
is built-in.
