Mauro Carvalho Chehab 54e339a960 [media] cx231xx: create DVB graph
cx231xx is simple with regards to DVB: all boards have just one
DVB adapter. So, we can use the default DVB helper function to
create the DVB media graph.

Mauro Carvalho Chehab 4155109aa8 [media] dvbdev: add a function to create DVB media graph
We need to create a DVB graph, linking the several DVB devnodes.

Add such function. Please notice that this helper function
doesn't take into account devices with multiple DVB adapters
and frontends.

For devices with multiple adapters, they should either create two
different media controller instances or to improve this function
to take the adapter ID into account.

Mauro Carvalho Chehab 3bde1b7840 [media] dvbdev: represent frontend with two pads
While on some devices the tuner is bound inside the frontend,
other devices use a separate subdevice for it.

So, in order to be more generic, better to map it with two
pads.

That will allows to use the media controller to lock the tuner
between the DVB and the V4L2 sub-drivers, on hybrid devices.

While here, change the logic to use pad 0 as sink for devices
with both sink and source pads.

We want to represent the links between the several DVB devnodes,

The DVB net devnode is a different matter, as it is not related
to the media stream, but with network. So, at least for now, let's

Mauro Carvalho Chehab 15d2042107 [media] Docbook: Fix documentation for media controller devnodes
The media-ctl userspace application assumes that all device nodes
are uniquelly defined via major,minor, just like v4l and fb.

That's ok for those types of devices, but, as we're adding support
for DVB at the API, what's written there at the DocBook is wrong.

So, fix it.

While here, fix the size of the reserved space inside the union,

Mauro Carvalho Chehab e31a0ba7df [media] media: Fix DVB devnode representation at media controller
The previous provision for DVB media controller support were to
define an ID (likely meaning the adapter number) for the DVB
devnodes.

This is just plain wrong. Just like V4L, DVB devices (and any other
device node)) are uniquely identified via a (major, minor) tuple.

This is enough to uniquely identify a devnode, no matter what
API it implements.

So, before we go too far, let's mark the old v4l, fb, dvb and alsa
"devnode" info as deprecated, and just call it as "dev".

We can latter add fields specific to each API if needed.

As we don't want to break compilation on already existing apps,
let's just keep the old definitions as-is, adding a note that
those are deprecated at media-entity.h.

Malcolm Priestley 743ab6a1cc [media] lmedm04: Create frontend call back for read status
Create dm04_read_status to check lock through either interrupt values
or directly by the call back.

When the device is not streaming the frontends original call back is
used. When streaming has started it turns off I2C messaging by
setting st->i2c_talk_onoff to zero. I2C can only be turn on again
by one of the other allowed frontend calls.

All old code is removed from lme2510_msg and this function only needs
to set st->i2c_talk_onoff to 1.

The lock status is saved and when the frondend is locked is maintained
by lme2510_int_response who will now just kill the lock.

The call back for rs2000 tuner is nologer required.

All frontend types have been tested.
