media: stkwebcam: deprecate driver, move to staging

This is a very old driver for very old hardware and it is one of
the very few remaining that does not use the vb2 framework (or
even the older videobuf framework), so deprecate this driver
and move it to staging with the intent to removing it altogether
by the end of 2022.

If someone wants to keep this driver, then it has to be converted
to use vb2.

media: move ttpci-eeprom to common

The ttpci-eeprom is actually an independent driver that

Revert "media: Kconfig: better support hybrid TV devices"

as it requires some adjustments.

So, let's revert it.

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.

media: usbvision: deprecate driver

The driver is deprecated and scheduled for removal by the end
of 2020. The reason is that this driver is for old and obsolete
hardware, and it produces a continuous stream of syzbot errors due
to poor code.

In order to prevent removal the following actions would have to
be taken:

- clean up the code
- convert to the vb2 framework
- fix the disconnect and free-on-last-user handling (i.e., add
a release callback for struct v4l2_device and rework the code
to use that correctly).

[media] tlg2300: move to staging in preparation for removal

This driver hasn't been tested in a long, long time. The company that made
this chip has gone bust many years ago and hardware using this chip is next
to impossible to find.

This driver needs to be converted to newer media frameworks but due to the
lack of hardware that's going to be impossible. Since cheap alternatives are
easily available, there is little point in keeping this driver alive.

In other words, this driver is a prime candidate for removal. If someone is

[media] sn9c102: prepare for removal by moving it to staging

During the last media summit meeting it was decided to move this driver to
staging as the first step to removing it altogether.

Most webcams covered by this driver are now supported by gspca. Nobody has the
hardware to convert the remaining devices to gspca.

This driver needs a major overhaul to have it conform to the latest frameworks
and compliancy tests.

Without hardware, however, this is next to impossible. Given the fact that
this driver seems to be pretty much unused (it has been removed from Fedora
several versions ago and nobody complained about that), we decided to drop
this driver.

This patch moves it to staging. Some time in 2014 we will drop it completely.

Properly handle tristate dependencies on USB/PCI menus

As USB/PCI/MEDIA_SUPPORT dependencies can be tristate, we can't
simply make the bool menu to be dependent on it. Everything below
the menu should also depend on it, otherwise, we risk to allow
building them with 'y', while only 'm' would be supported.

So, add an IF just before everything below, in order to avoid
such risks.

[media] media/usb: fix kconfig dependencies

(a.k.a. Kconfig bool depending on a tristate considered harmful)
Fix various build errors when CONFIG_USB=m and media USB drivers
are builtin. In this case, CONFIG_USB_ZR364XX=y,
CONFIG_VIDEO_PVRUSB2=y, and CONFIG_VIDEO_STK1160=y.
This is caused by (from drivers/media/usb/Kconfig):
menuconfig MEDIA_USB_SUPPORT
bool "Media USB Adapters"
depends on USB && MEDIA_SUPPORT
=m =y
so MEDIA_USB_SUPPORT=y and all following Kconfig 'source' lines
are included. By adding an "if USB" guard around most of this file,
the needed dependencies are enforced.

[media] au0828: remove forced dependency of VIDEO_AU0828 on VIDEO_V4L2

This patch removes the dependendency of VIDEO_AU0828 on VIDEO_V4L2 by
creating a new Kconfig option, VIDEO_AU0828_V4L2, which enables analog
video capture support and depends on VIDEO_V4L2 itself.
With VIDEO_AU0828_V4L2 disabled, the driver will only support digital
television and will not depend on the v4l2-core. With VIDEO_AU0828_V4L2
enabled, the driver will be built with the analog v4l2 support included.
By default, the VIDEO_AU0828_V4L2 option will be set to Y, so as to
preserve the original behavior.
