There are too many firmwares there. As we need to add
MODULE_FIMWARE() macros, the better is to define their names
on just one place and use the macros for both cards/device type
tables and MODULE_FIRMWARE().

Instead of complaining, just silently discard those messages, instead of

A proper fix is to put the device on suspend/power down mode when the module

There is an special lookup code that is called when
SMS_BOARD_UNKNOWN. The logic there is bogus and will cause
an oops, as .type is SMS_UNKNOWN_TYPE (-1).
As the code would do:
return smscore_fw_lkup[type][mode];
That would mean that it would try to go past the
smscore_fw_lkup table.
So, just remove that bogus code, simplifying the logic.

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.
While here, also simplifies a little bit the logic and print
a message if an user-selected mode doesn't exist.

Implement poll() method for debugfs and be sure that the
debug_data won't be freed on ir or on read().
With this change, poll() will return POLLIN if either data was
filled or if data was read. That allows read() to return 0
to indicate EOF in the latter case.

This seems to be ever broken. That's the status report with
Firmware 2.1, before adding support for sms2270 is:
[22273.787218] smsdvb_onresponse: MSG_SMS_GET_STATISTICS_RES
[22273.792592] IsRfLocked = 1
[22273.792592] IsDemodLocked = 1
...
[22273.792598] TransmissionMode = -64
...
(all unshown fields are filled with zeros)
Of course, transmission mode being a negative number is wrong.
So, we need to take a deeper look on it.
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.

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.

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.
