Adding support for the media controller for a pure DVB device
is simple: just create a struct media_device and add it to the
dvb adapter. After creating all DVB devices, we need to call
the DVB core, for it to create the media graph.
More work is needed for pure DVB tuners, but this is hidden
at the Siano driver, just like several others non-hybrid
devices. So, this is streight forward.

The btcx-risc module is no longer used by other drivers except for bttv.

The basic API of rc-core used to be:
dev = rc_allocate_device();
dev->x = a;
dev->y = b;
dev->z = c;
rc_register_device();
which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:
dev = rc_allocate_device();
dev->x = a;
rc_set_allowed_protocols(dev, RC_BIT_X);
dev->z = c;
rc_register_device();
There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

Remove the CONFIG_ prefix from two Kconfig symbols in a dependency for
SMS_SIANO_DEBUGFS. This prefix is invalid inside Kconfig files.
Note that the current (common sense) dependency on SMS_USB_DRV and
SMS_SDIO_DRV being equal ensures that SMS_SIANO_DEBUGFS will not
violate its constraints. These constraint are that:
- it should only be built if SMS_USB_DRV is set;
- it can't be builtin if USB support is modular.
So drop the dependency on SMS_USB_DRV, as it is unneeded.

building with:
CONFIG_USB=m

Hauppauge Nova-S-Plus DVB-S model 92001 does not lock on horizontal
polarisation. According with the info provided at the BZ, model
92002 does.
The difference is that, on model 92001, the tone select is done via
isl6421, while, on other devices, this is done via cx24123 code.
This patch adds a way to override the demod's set_tone at isl6421
driver. In order to avoid regressions, the override is enabled
only for cx88 Nova S plus model 92001. For all other models and
devices, the set_tone is provided by the demod driver.
Patch originally proposed at bz@9476[1] by Michel Meyers and
John Donoghue but applying the original patch would break support
for all other devices based on isl6421.

There are two ways to specify firmware for siano devices: a
per-device ID and a per-device type.
The per-device type logic is currently made by a 11x9 string
table, sparsely filled. It is very hard to read the table at
the source code, as there are too much "none" filling there
("none" there is a way to tell NULL).
Instead of using such problematic table, convert it into an
easy to read table, where the unused values will be defaulted
to NULL.

With the debugfs patches applied, it is possible to see that, instead
of filling StatisticsType with 5, and FullSize with the size of the
payload (this is what happens with sms2270 and firmware 8.1),
those fields are also initialized with zero:
StatisticsType = 0 FullSize = 0
IsRfLocked = 1 IsDemodLocked = 1 IsExternalLNAOn = 0
SNR = 0 dB RSSI = 0 dBm InBandPwr = 0 dBm
CarrierOffset = 0 Bandwidth = 0 Frequency = 0 Hz
TransmissionMode = -64 ModemState = 0 GuardInterval = 0
SystemType = 0 PartialReception = 0 NumOfLayers = 0
SmsToHostTxErrors = 0
The data under "TransmissionMode" varies according with the signal,
and it is negative. It also matches the value for InBandPwr when
the tuner is on DVB-T (ok, signal doesn't lock, but the power level
should be about the same with the antena fixed, and measured at about
the same time).
So, there's a very high chance that, when StatisticsType is zero, the
signal strength is at the same position as Transmission Mode.
So, discard all other parameters, and provide only signal/rf lock and
signal strength if StatisticsType is 0, for ISDB-T.

Right now, the driver sends DVB data even before tunning.
It was noticed that this may lead into some mistakes at DVB
decode, as the PIDs from wrong channels may be associated with
another frequency, as they may already be inside the PID buffers.
So, prevent it by not feeding DVB demux with data while there's no
feed or while the device is not tuned.

It was expected that the bandwidth would be following the defines
at smscoreapi.h. However, this doesn't work. Instead, this field
brings just the bandwidth in MHz. Convert it to Hertz.
It should be noticed that, on ISDB, using the _EX request, the
field TuneBW seems to show the value that matches the bandwidth
code.

The check for lock logic is broken. Due to that, no PER/BER
stats will ever be showed, and the DVBV3 events will be wrong.
Also, the per-layer PER/BER stats for ISDB-T are filled with
the wrong index.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
There are a number of small issues with the stats refactoring:
- InBandPwr better represents the signal strength;
- Don't zero signal strength /cnr if no lock;
- Fix signal strength/cnr scale;
- Don't need to fill PER/BER if not locked, as the
code will disable those stats anyway.

While this frontend provides a nice set of statistics, the
way it is currently reported to userspace is poor. Worse than
that, instead of using quality indicators that range from 0 to 65535,
as expected by userspace, most indicators range from 0 to 100.
Improve it by using DVBv5 statistics API. The legacy indicators
are still reported using the very same old way, but they're now
using a proper range (0 to 65535 for quality indicadors; 0.1 dB
for SNR).

It is confusing to merge both status updates with debug stuff.
Also, it is a better idea to move those status updates to
debugfs, instead of doing a large amount of printk's like that.
So, break them into a separate block of routines.

Instead of handling both DVB-T and ISDB-T at the same get_frontend
function, break it intow one function per-delivery system.
That makes the code clearer as we start to add support for DVBv5
statistics, and for ISDB-T get frontend stuff.

Currently, every time a message is sent or received, the endiannes
need to be fixed on big endian machines. This is currently done
on every call to the send API, and on every msg reception logic.
Instead of doing that, move it to the send/receive functions.
That simplifies the logic and avoids the risk of forgetting to
fix it somewhere.

The old statistics request don't work with newer firmwares.
Add a logic to use the newer stats if firmware major is 8.
Note that I have only 2 devices here, one with firmware 2.1
(Hauppauge model 55009 Rev B1F7) and another one with
firmware 8.1. We may need to adjust the firmware minimal
version for the *_EX message variants, as we start finding
firmware versions between 2.x and 8.x.

Instead of re-use tune_done also for stats, the better is to use
