436ae1381e V4L/DVB (11934): Change order for FM tune
Change order data of buffer in FM simple_tune function. It is usefull for:

1. Set data of tuner with CP bit UP. 0xCE for MK5 or 0xC6 for MK3
2. When call simple_fm_tune, read this byte from config and overwrite
this byte in function simple_radio_bandswitch for set CP bit to OFF.

Of course it can be usefull for other tuner for overwrite default
settings of FM.

0a863975e2 V4L/DVB (11918): tuner-xc2028: Fix offset frequencies for DVB @ 6MHz
Both ATSC and DVB @ 6MHz bandwidth require the same offset.

While we're fixing it, let's cleanup the bandwidth setup to better
reflect the fact that it is a function of the bandwidth.

Thanks to Terry Wu <terrywu2009@gmail.com> for pointing this issue and
to Andy Walls <awalls@radix.net> for an initial patch for this fix.

a1014d70db V4L/DVB (11917): Fix firmware load for DVB-T @ 6MHz bandwidth for xc3028/xc3028L
The only two countries that are known to use 6MHz bandwidth are Taiwan
and Uruguay. Both use QAM subcarriers at OFTM.

This patch fixes the firmware load for such countries, where the
required firmware is the QAM one.

This also confirms the previous tests where it was noticed that the 6MHz
QAM firmware doesn't work for cable. So, this patch also removes support
for DVB-C, instead of just printing a warning.

Thanks to Terry Wu <terrywu2009@gmail.com> for pointing this issue and
to Andy Walls <awalls@radix.net> for an initial patch for this fix.

a37791c540 V4L/DVB (11804): xc5000: poll at 5ms interval for register write command completion
Instead of polling at 100ms intervals for register writes, poll at 5ms
intervals.  This is consistent with the xc5000 specification, and improves
tuning time by up to 500 ms on devices that such as the au0828 which do not
properly implement i2c clock stretching (since the five register writes that
occur for a tuning request often do not complete immediately but do complete
far before 100ms has gone by).

The net amount of time we wait before timing out is unchanged (500ms).

f911eab66d V4L/DVB (11261): saa7146: Remove buffer type check from vidioc_g_parm
The v4l2-ioctl core now only allows buffer types for which the
corresponding ->vidioc_try_fmt_xxx() methods are defined to be used with
vidioc_(g|s)_parm.

The driver was only allowing VIDEO_CAPTURE buffers for g_parm, but since
the driver defines ->vidioc_try_fmt_vid_overlay() it will now allow
VIDEO_OVERLAY buffers as well.  This should be fine as the fields the
driver fills in, readbuffers and frame rate, aren't wrong for VIDEO_OVERLAY
buffers.

cf47d878e5 V4L/DVB (11236): tda827x: fix locking issues with DVB-C
Separate tuning table for DVB-C solves tuning problem at 388MHz

TechnoTrend C-1501 DVB-C card does not lock on 388MHz. I assume that
existing frequency table is valid for DVB-T.

This is suggested by the name of the table: tda827xa_dvbt.

Added a table for DVB-C with the name tda827xa_dvbc.

Added runtime selection of the DVB-C table when the tuner is type
FE_QAM.

This should leave the behaviour of this driver with with DVB_T tuners
unchanged. This modification is in file tda827x.c

The tda827x.c gives the following warning message when debug=1:

tda827x: tda827x_config not defined, cannot set LNA gain!

Solved this by adding a tda827x_config struct in budget-ci.c.

Hybrid card, possibly for other AVerMedia Cardbus cards.

The I2C address 0x40 doesn't like the SAA7134's 0xfd quirk, so it was
disabled.

7d979a86a9 V4L/DVB: calibration still successful at 10
With while (i++ < 10) { ... } i can reach 11, so callibration still
succeeds at i == 10.

68d5ce7021 V4L/DVB (10504): tda827x: Be sure that gate will be open/closed at the proper time
The gate control logic is broken: several routines just keep it open;
other rotines close it properly; there are even other routines that
assumes that it is open without really checking or opening it.

Instead of having to manually handle the gate control and having such
troubles, let a sub-routine take care of the gate, opening it before
i2c_transfer and closing it after that. This avoids leaving the gate
into a random state.
