If I2C is present and it is module, the DVB core should also
be a module, otherwise build will now fail with:

Enabling CONFIG_DVB_MMAP without CONFIG_VIDEOBUF2_VMALLOC results
in a link error:

drivers/media/dvb-core/dvb_vb2.o: In function `_stop_streaming':
dvb_vb2.c:(.text+0x894): undefined reference to `vb2_buffer_done'

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.

On several places, whitespaces are being used for indentation,
or even at the end of the line.

Fix them.

There is no dependency between the two, so remove the dependency in
Kconfig files.

<title>media: cec-pin: add low-level pin hardware support</title>

<id>urn:sha1:ea5c8ef296681b53480ebeeffd06083bb60e693d</id>
<content type='text'>
Add support for CEC hardware that relies on low-level pin polling or
GPIO interrupts.

One example is the Allwinner SoC. But any GPIO-based CEC implementation can
use this as well.

A GPIO implementation is very suitable as well for debugging: it can use
interrupts to detect state changes and report it. Userspace can then verify
if the bus traffic is correct. This also makes error injection possible.

The disadvantage is that it is hard to get the timings right since linux
isn't a hard realtime system.

In general on an idle system it works quite well, but under load the timer
will miss its mark every so often.

The debugfs file /sys/kernel/debug/cec/cecX/status gives some statistics
with respect to the timer overruns.

When the adapter is unconfigured and the low-level driver supports
interrupts, then the interrupt will be used to detect changes. This should
be quite accurate. But when the adapter is configured a hrtimer has to be
used.

The hrtimer implements a state machine where for each state the code will
read the bus or drive the bus and go on to the next state. It will re-arm
the timer with a delay based on the next state.

<content type='text'>
This config option is strictly speaking independent of the
media subsystem since it can be used by drm as well.

Besides, it looks odd when drivers select CEC_CORE and
MEDIA_CEC_NOTIFIER, that's inconsistent naming.

<title>[media] cec: select CEC_CORE instead of depend on it</title>

<id>urn:sha1:9177e51d1434076a91f9bfb693deae8b955d6d57</id>
<content type='text'>
The CEC framework is used by both drm and media. That makes it tricky
to get the dependencies right.

This patch moves the CEC_CORE and MEDIA_CEC_NOTIFIER config options
out of the media menu and instead drivers that want to use CEC should
select CEC_CORE and MEDIA_CEC_NOTIFIER (if needed).
