Fronted and Tuner Driver for ITE IT913x Series with inital support for
IT9137 integrated demodulator and tuner device.
The driver is loosely based on AF9035 series. However, support is not intended for
this device specificity.
The IT9137 tuner has been tested on UHF bands, but VHF has only been simulated.
Possible TODO the tuner sections may be separated from the main driver. All future devices
should use the it913x_fe_script_loader for other tuner devices.

Siano modules already had sms_dbg flag which is a module parameter which
sets the debug mode so module prints messages to dmesg for debugging.
The variable was static therefore apply only to the file which defines
the module. In modules as smsmdtv.ko that contain a few files, the debug
flag applied only for functions in that main file.
flag was changed to be non-static and therefore can be accessed by all
module files (although it is still not exported out of the module).

Rather than dumping out hex values, lets print the actual calculated
frequency and period the hardware has been configured for. After this
[ 2643.276215] mceusb 3-1:1.0: tx data: 9f 07 (length=2)
[ 2643.276218] mceusb 3-1:1.0: Get carrier mode and freq
[ 2643.277206] mceusb 3-1:1.0: rx data: 9f 06 01 42 (length=4)
[ 2643.277209] mceusb 3-1:1.0: Got carrier of 37037 Hz (period 27us)
Matches up perfectly with the table in Microsoft's docs.
Of course, I've noticed on one of my devices that the MS-recommended
default value of 1 for carrier pre-scaler and 66 for carrier period was
butchered, and instead of converting 66 to hex (0x42 like above), they
put in 0x66, so the hardware reports a default carrier of 24390Hz.
Fortunately, I guess, this particular device is rx-only, but I wouldn't
put it past other hw to screw up here too.

According to the specs, you can read the number of tx ports, number of
rx sensors, which tx ports have cables plugged into them, and which rx
sensors are active. In practice, most of my devices do seem to report
sane values for tx ports and rx sensors (but not all -- one without any
tx ports reports having them), and most report the active sensor
correctly, but only one of eight reports cabled tx ports correctly. So
for the most part, this is just for informational purposes.

Supposedly, there are essentially three different classes of devices
that are compatible with Microsoft's specs. First are the "legacy"
devices, which are built using Microsoft-provided hardware specs and
firmware. Second are "emulator" devices, which are built using custom
hardware and firmware, written to emulate Microsoft's firmware. Third
are "port" devices, which have their own device driver and firmware,
which provides compatible data to higher levels of the stack.
>From what I can tell, things like nuvoton-cir and fintek-cir are
essentially "port" devices -- their raw IR buffer format is very similar
to that of the mceusb devices. Now, within the mceusb driver, we have
three different "generations", which at first, seemed like maybe they
mapped to emulator versions. Unfortuantely, every single device I have
responds "illegal command" to the query to get firmware emulator version
from the hardware, which means they're either all emulator version 1, or
they're legacy devices, and our different "generations" aren't at all
related here. Though in theory, its possible the gen1 devices are
"legacy" devices and the rest are emulator v1. There are some useful
features of the v2 interface I was hoping to play with, but alas...

Hello,
When migrating from Slackware 13.1 to 13.37 (kernel 2.6.33.x to
2.6.37.6), there was some sort of regression with the external webcam
installed at the notebook (0x45:6128, SN9C325+OM6802).
In the version 2.6.37.6, the images got *very* dark, making the webcam
almost unusable, unless if used with direct sunlight.
Tracing back what happened, I concluded that changeset 0e4d413af
caused some sort of odd effects - including this - to this specific model.

The logic at em28xx_isoc_dvb_max_packetsize() sucks, at least for newer
the needed packet size. Yet, it is better than nothing.
Rewrite the code in order to change the default to 752 for em2884 and
newer chips and provide a better way to handle per-chipset specifics.
For em2874, the current default should be enough, as the only em2874
board is currently a 1-seg ISDB-T board, so, it needs only a limited
amount of bandwidth.

Currently, the driver assumes that all QAM carriers are spaced with
8MHz. This is wrong, and may decrease QoS on Countries like Brazil,
that have DVB-C carriers with 6MHz-spaced.
Fortunately, both ITU-T J-83 and EN 300 429 specifies a way to
associate the symbol rate with the bandwidth needed for it.
For ITU-T J-83 2007 annex A, the maximum symbol rate for 6 MHz is:
6 MHz / 1.15 = 5217391 Bauds
For ITU-T J-83 2007 annex C, the maximum symbol rate for 6 MHz is:
6 MHz / 1.13 = 5309735 Bauds.
As this tuner is currently used only for DRX-K, and it is currently
hard-coded to annex A, I've opted to use the roll-off factor of 0.15,
instead of 0.13.
If we ever support annex C, the better would be to add a DVB S2API
call to allow changing between Annex A and C, and add the 0.13 roll-off
factor to it.
This code is currently being used on other frontends, so I think we
should later add a core function with this code, to warrant that
it will be properly implemented everywhere.
