<title>media: Kconfig: cleanup VIDEO_DEV dependencies</title>

<id>urn:sha1:9958d30f38b96fb763a10d44d18ddad39127d5f4</id>
<content type='text'>
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) &amp;&amp; VIDEO_DEV
		select RATIONAL
		select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
		default (I2C || I2C=n) &amp;&amp; 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.

<id>urn:sha1:4bdbff4da40584ec2225bb429b7c66ad54d19cda</id>
<content type='text'>
There are three tuners that depend on some functions inside
V4L2 core:

	$ git grep -l -E 'v4l2_[0-9a-zA-Z_]+\(' drivers/media/tuners/
	drivers/media/tuners/e4000.c
	drivers/media/tuners/fc2580.c
	drivers/media/tuners/msi001.c

Make them dependent of VIDEO_V4L2, as otherwise, this would happen:

	on x86_64:
	CONFIG_VIDEO_V4L2=m
	CONFIG_MEDIA_TUNER_E4000=y

<content type='text'>
There are *lots* of I2C ancillary drivers. While we're using
comments to group them, all options appear at the same menu.

It should be a lot clearer to group them into sub-menus, with
may help people to go directly to the driver(s) he's needing
to enable.

<title>media: Clarify how menus are hidden by SUBDRV_AUTOSELECT</title>

<id>urn:sha1:4fa4ef39e1c48b576a6a7f49c7410277e7ba09fa</id>
<content type='text'>
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.

<title>media: Kconfig: allow to select drivers if EMBEDDED</title>

<id>urn:sha1:8169cf0a02caafd87ee33e66c12f7a35606a6b0c</id>
<content type='text'>
Embedded systems often connect to sensors or other multimedia
subdevices directly. Currently, to be able to select such a
subdevice (e.g. CONFIG_VIDEO_OV5640) disabling of the auto-
select config option is needed (CONFIG_MEDIA_SUBDRV_AUTOSELECT).

This is inconvenient as the ancillary drivers for a particular
device then need to be selected manually.

Allow to select drivers manually while keeping the auto-select
feature in case EXPERT (selected by EMBEDDED) is enabled.
