V4L/DVB (12613): cx25840: fix determining the firmware name
Depending on the model there are three different firmwares to choose from.
Unfortunately if a cx23885 is loaded first, then the global firmware name
is overwritten with that firmware and if ivtv is loaded next, then it
tries to load the wrong firmware. In addition, the original approach would
also overwrite any firmware that the user specified explicitly.

V4L/DVB (12600): dvb-usb-remote: return KEY_RESERVED if there's free space for new keys
The input subsystem checks if get_keycode works for a scan code. Due to that,
we need to return a valid value when there's some space at the table that
can be used by a scancode.
V4L/DVB (12599): dvb-usb-remote: Allow dynamically replacing the IR keycodes
Implements handler for EVIOCGKEYCODE/EVIOCSKEYCODE via adding two new callbacks
to the input device.
Since on dvb-usb a scan code has 16 bits, to fulfill rc5 standard codes, the default
getkeycode/setkeycode input methods would require the driver to spend up to 64 Kb of
a sparse table. Instead, add two new callbacks to the event device.
With this, it is now possible to replace the keycode tables. There are, however, a few
implementation details at the current patch:
1) It will replace the existing device keytable, instead of creating an instance
of the data. This works. However, if two devices pointing to the same table
were connected, changing the IR table of one will also change the IR table for
the other (the solution for this one is simple: just kmalloc some memory);
2) In order to change the scan code, you need first to change the key to
KEY_RESERVED or KEY_UNKNOWN to free some space at the table (solution: allocate
some additional space for newer scan codes or allow dynamic table grow);
3) The table size cannot be extended. It would be easy to allow the table to
grow dynamically: just calling kmalloc(size+1); kfree(old). Yet, maybe we can
just create a bigger table with a fixed size, like for example a table with 128
entries. This should be enough even for a very big IR.
The current issues should be addressed on a later patch.
V4L/DVB (12598): dvb-usb: store rc5 custom and data at the same field
In order to be closer to V4L IR implementation, it is needed to replace
u8 custom, data
to:
u16 scan
This allows using non-rc5 mappings, like the 8 bit keycodes used on older
protocols. It will also allow future implementations of rc6 keystrokes
when needed.
V4L/DVB (12595): common/ir: use a struct for keycode tables
Currently, V4L uses a scancode table whose index is the scancode and
the value is the keycode. While this works, it has some drawbacks:
1) It requires that the scancode to be at the range 00-7f;
2) keycodes should be masked on 7 bits in order for it to work;
3) due to the 7 bits approach, sometimes it is not possible to replace
the default keyboard to another one with a different encoding rule;
4) it is different than what is done with dvb-usb approach;
5) it requires a typedef for it to work. This is not a recommended
Linux CodingStyle.
This patch is part of a larger series of IR changes. It basically
replaces the IR_KEYTAB_TYPE tables by a structured table:
struct ir_scancode {
u16 scancode;
u32 keycode;
};
This is very close to what dvb does. So, a further integration with DVB
code will be easy.
While we've changed the tables, for now, the IR keycode handling is still
based on the old approach.
The only notable effect is the redution of about 35% of the ir-common
module size:
text data bss dec hex filename
6721 29208 4 35933 8c5d old/ir-common.ko
5756 18040 4 23800 5cf8 new/ir-common.ko
In thesis, we could be using above u8 for scancode, reducing even more the size
of the module, but defining it as u16 is more convenient, since, on dvb, each
scancode has up to 16 bits, and we currently have a few troubles with rc5, as their
scancodes are defined with more than 8 bits.
This patch itself shouldn't be doing any functional changes.

V4L/DVB (12567): ir-keymaps: use KEY_CAMERA for snapshots
KEY_CAMERA is already used for a long time with webcam drivers to take a picture.
On other media drivers, due to the lack of a snapshot button, random KEY codes
were sent, being KEY_SHUFFLE the most used one, probably due to cut-and-paste
from other remotes, since one of them uses the same key for snapshot and shuffle.
The better is to use KEY_CAMERA on all drivers solving this issue. This
follows the IR standard map as defined at:
http://linuxtv.org/wiki/index.php/Remote_Controllers
Each remote were using a different keycode for timeshift. Use the same
keycode for all of them, using the map as defined at:

The ir-keymaps.c has frequent additions. As people tend to copy an old
keyboard entry, a bad CodingStyle at an ancient entry may result on a
freshly bad CodingStyle patch.
So, better to fix the CodingStyle for the entire file.

V4L/DVB (12482): firedtv: add PID filtering for SW zigzag retune
The AVC protocol uses the same command for tuning and PID filtering and
since dvb-core uses a software zigzagging to do automatic retuning this
could cause all PID filters to be cleared. PID filter information is
now included in all DSD commands to the card.
Background:
There is a problem in the firedtv driver that causes recordings to stop
if the SW zigzag algorithm in dvb-core kicks in with a retune after the
application has set up the PID filters. Since tuning and setting PID
filters uses the same AVC command (DSD) and only the replace subfunction
is supported by the card, it is not possible to do a retune without
setting the PID filters. This means that the PID filtering has to be
sent in each tune.
This problem applies to C and T cards since S and S2 cards tune using a
vendor specific command. The patch corrects the problem by sending the
PID list in each tune. I have tested it on my T card with a good
result.
How to trigger problem: Zap to a channel and output AV to a file, e.g.
"tzap -c channels.conf SVT1 -r -o SVT1.ts". After a short while, pull
the antenna cable from the card. The lock on the channel will disappear
and the TS file will stop increasing in size. Wait a couple of seconds.
Replug the cable again. You will get a lock on the channel again, but
the TS file will never increase in size agains sinze no PIDS are
filtered.
Tested with kaffeine with DVB-T and DVB-C: Fixes retuning after antenna
was plugged out and back in with DVB-T. Does not fix this with DVB-C,
but also doesn't regress on DVB-C.
