Those boards were missing the ISDB-T support.
Most of the work on this patch were done by Alfredo.
My work here were to port this patch from Kernel 3.2 to upstream,
fix the issue caused by the set_frontend bad hook, and add the
Kconfig bits.
Tested on a X8502 board rebranded as:
"Leadership - Placa PCI-e de Captura de Vídeo Híbrida" - product code 3800.

changeset 768e6dadd74 caused a regression on using mb86a20s
in parallel mode, as the parallel mode selection got
overriden by mb86a20s_init2.

When the frontend drivers got converted to DVBv5 API, the original
hook that tracked when a frontend is set got removed, being replaced
by an approach that would use the gate control. That doesn't work
fine with some boards. Also, the code were called more times than
desired.
Replace it by a logic that will hook the dvb set_frontend ops,
with works with both DVBv3 and DVBv5 calls.
Tested on a Mygica X8502 OEM board.

Note that with the rc-feedback trigger, the cir-rx trigger is now
redundant. The cir-tx trigger is not used by default; if this
functionality is desired then it should exist in rc-core, not in
a driver.

Hello,
this is a new gspca driver for Syntek STK1135 webcams. The code is completely
new, but register values are based on Syntekdriver (stk11xx) by Nicolas VIVIEN
(http://syntekdriver.sourceforge.net).
Only one webcam type is supported now - vendor 0x174f, device 0x6a31.
It's Asus F5RL laptop flippable webcam with MT9M112.
The camera works better than in Windows - initializes much faster and
provides more resolutions (the sensor can do almost any resolution - just
add it to the stk1135_modes[] - could this feature be somehow used by
applications to avoid SW scaling?).
Autoflip works too - when the camera is flipped around, the image is flipped
automatically.

sd_start() operates on device controls but after the conversion to the
v4l2 control framework in commits 62bba5d and 1bd7d6a controls are
initialized in sd_init_controls() which is called _after_ sd_init():
The change fixes a NULL pointer dereference for Hercules Blog Webcam;
the problem is observable since 3.6:

Allow stepless synthesizer configuration. With that change we lose
precision a little bit, as it is now between +-500Hz from the target.
It could be better but on that case calculation algorithm goes more
complex and atm there is more important things to do.
Two approach to improve which comes to my mind are:
1) select and use biggest suitable step
2) use greatest common divisor algo to find divisor for thresh & frac
when possible to avoid rounding errors, which is root of cause of
current +-500Hz inaccuracy.

It looks like there is some extra data carried to enhance sampling
results. When you tune to some some weak/empty channel those bits
are always zeroes. When you tune to some channel where is very
strong signals those bits are all zeroes.
Examining those 32-bits reveals shortly there is 16 pieces of 2-bit
numbers. Number seen are 0, 1 and 3 - for some reason 2 is not used.
I used that number to shift bits given amount to left, "increasing"
sampling resolution by 3-bits. It may be wrong, but after some testing
it still provides better signal.
