Some (North American) providers use a non-standard mode called
"8psk turbo fec". Since there is no flag in the driver that
would allow an application to determine whether a particular
device can handle "turbo fec", the attached patch introduces
FE_CAN_TURBO_FEC.
Since there is no flag in the SI data that would indicate
that a transponder uses "turbo fec", VDR will assume that
all 8psk transponders on DVB-S use "turbo fec".

My previous patch to depend on FONTS was not sufficient since
FONTS is boolean. VIDEO_VIVI needs to depend on a tristate so that
it won't be enabled as =y when framebuffer is built as modular, so
modify it to depend on the same symbols that FONTS depends on, which
are FRAMEBUFFER_CONSOLE || STI_CONSOLE.
Fixes this build error when VIDEO_VIVI=y and FRAMEBUFFER_CONSOLE=m:

I have pinnacle hardware now. None of this pinnacle-specific crap is at
all necessary (in fact, some of it needed to be removed to actually make
it work). The only thing unique about this device is that it often
transfers inbound data w/a header of 0x90, meaning 16 bytes of IR data
following it, so I had to make adjustments for that, and now its working
perfectly fine.

The first-gen mceusb device init code, while mostly functional, had a few
issues in it. This patch does the following:
1) removes use of magic numbers
2) eliminates mapping of memory from stack
3) makes debug spew translator functional
Additionally, this clean-up revealed that we cannot read the proper default
tx blaster bitmask from the device, we do actually have to initialize it
ourselves, which requires use of a somewhat gross list-based mask inversion
check.
This patch also removes the entirely unnecessary use of struct ir_input_state.
Also supersedes two earlier patches that also touched on first-gen
cleanup, but were partially botched. This one actually compiles, works,
etc., I swear. ;)

This patch moves the state from each raw decoder into the
ir_raw_event_ctrl struct.
This allows the removal of code like this:
spin_lock(&decoder_lock);
list_for_each_entry(data, &decoder_list, list) {
if (data->ir_dev == ir_dev)
break;
}
spin_unlock(&decoder_lock);
return data;
which is currently run for each decoder on each event in order
to get the client-specific decoding state data.
In addition, ir decoding modules and ir driver module load
order is now independent. Centralizing the data also allows
for a nice code reduction of about 30% per raw decoder as
client lists and client registration callbacks are no longer
necessary (but still kept around for the benefit of the lirc
decoder).
Out-of-tree modules can still use a similar trick to what
the raw decoders did before this patch until they are merged.

While rc-5 and rc-6 protocols are generally abreviated as "rc5" and "rc6",
previous sysfs nodes uses rc-5 and rc-6 for the Philips protocols. This is
consistent with the protocol nomenclature given by the original Philips
spec: "Remote control system RC-5" (doc. Nr. 9398 706 23011).
Also, rc5 is the name of a widely known cryptography protocol.
So, the better is to keep referring to those protocols as "rc-5" and "rc-6".

With the current logic, each raw decoder needs to add a copy of the exact
same sysfs code. This is both unnecessary and also means that (re)loading
an IR driver after raw decoder modules have been loaded won't work as
expected.
This patch moves that logic into ir-raw-event and adds a single sysfs
file per device.
Reading that file returns something like:
"rc5 [rc6] nec jvc [sony]"
(with enabled protocols in [] brackets)
Writing either "+protocol" or "-protocol" to that file will
enable or disable the according protocol decoder.
An additional benefit is that the disabling of a decoder will be
remembered across module removal/insertion so a previously
disabled decoder won't suddenly be activated again. The default
setting is to enable all decoders.
This is also necessary for the next patch which moves even more decoder
state into the central raw decoding structs.

If the firmware has failed, this patch will automatically reload &
restart the card. The previous card state will be restored on a
successful restart. Firmware reload will only happen if neither the
encoder or decoder is active. If the card is busy then behaviour is as
before, returning -EIO on device access until the reload can occur. On
cards that support video output, coloured bars will be displayed during
the reload.

>From Ian's e-mail:
When a device is opened the firmware state will be checked. If it isn't
responding then the open will fail with -EIO. Due to the nature of the
hardware, a single failed check will block everything since we don't know
exactly what has failed. A side effect of this is the blocking of debug
access, so an additional debug level has been created which allows the block
to be bypassed.
Andy Walls' modifications:
I modified Ian's patch to add a separate fw_debug module parameter to change
the driver's behavior, as opposed to using the normal debug module parameter.
The fw_debug module parameter is only available when CONFIG_VIDEO_ADV_DEBUG
is set.
I also made some minor whitespace adjustments and changed some warning
