For some reason the /dev/radio device was implemented as an exclusive open:
you could open it only once and not a second time.

As per the feature removal document, make the tuner type check more strict
so that it is no longer possible to set the radio frequency through a video
node or the TV frequency through a radio node.

The omap_vout driver has an output overlay, but never advertised that
capability.
The driver should also set the V4L2_FBUF_FLAG_OVERLAY flag.

The changeset 240ab508aa is incomplete, as the first thing that
happens at cache clear is to do a memset with 0 to the cache.
So, the delivery system needs to be explicitly preserved there.

As reported by Lawrence[1], MythTV 0.24.1 does the wrong thing
with a DVBv5 call: it fills the delivery system with
SYS_UNDEFINED, expecting that the DVB core would work with that.
This used to work by accident, as the DVB core were missing the
check for the supported delivery systems. Yet, fixing it
is easy, so let's add a logic to handle this case, to
provide backward compatibility.

It even uses even Cypress FX2, general USB bridge chip, default IDs
that makes driver load all FX2 devices having default ID...

Some time ago, Manoel sent us a patch adding more stuff
to the init sequence. However, his patch were also doing
non-related stuff, by changing the init logic without
any good reason. So, it was asked for him to submit a
patch with just the data that has changed, in order to
allow us to better analyze it.
As he didn't what it was requested, I finally found some
time to dig into his init sequence and add it here.
Basically, new stuff is added there. There are a few changes:
1) The removal of the extra (duplicated) logic that puts
the chip into the serial mode;
2) Some Viterbi VBER measurement init data was changed from
0x00 to 0xff for layer A, to match what was done for
layers B and C.
None of those caused any regressions and both make sense
on my eyes.
The other parameters additions actually increased the
tuning quality for some channels. Yet, some channels that
were previously discovered with scan disappered, while
others appeared instead. This were tested in Brasilia,
with an external antena.
At the overall, it is now a little better. So, better to
add these, and then try to figure out a configuration that
would get even better scanning results.

As a DVBv3 application may be relying on the delivery system,
don't reset it at DTV_CLEAR. For DVBv5 applications, the
delivery system should be set anyway.

This remote is shipped with various Compro cards, not this one only.
Furthermore this remote can be bought separately under name Compro
VideoMate K100.

Add driver for the JPEG codec IP block available in Samsung Exynos SoC series.
The driver is implemented as a V4L2 mem-to-mem device. It exposes two video
nodes to user space, one for the encoding part, and one for the decoding part.
