Matt Doran 8f6956c7f9 V4L/DVB (5960): Add module parameter to enable SFN workaround
In some areas in the world the broadcasters are not using the same
cellid for each transmitter in a SFN. The DiBcom has problems with
that setup. The module parameter buggy_sfn_workaround makes it re-usable.

Patrick Boettcher 01373a5c97 V4L/DVB (5955): Add support for DiB7070-based devices
This changeset adds support for DiB7070P-based devices by adding the
dib0070-driver and putting the appropriate layouts into
dib0700_devices.c

It also includes a new firmware for the dib0700 which is necessary to
make the DiB7070-boards work and it also should fix the i2c-problems
on some boards.

Patrick Boettcher b6884a17fc V4L/DVB (5954): Sync with DiBcom Driver Release 2.1.3 + some improvements
This changesets syncs the OpenSource driver for DiBcom demodulators
with version 2.1.3 of DiBcom reference driver. There were some
improvements since the last release for linux-dvb, e.g.:

- stepped AGC startup
- less space for initialization
- diversity synchronization

Furthermore this changeset contains the following things:

- latest AGC settings for MT2266-based devices (namely Nova-TD and other) will improve the sensitivity
- support for STK7700D reference design in dib0700-devices
- remove some line-breaks when debugging is enabled
- getting rid of layer between frontend_parameters and ofdm_channel used in dib*-drivers

This adds support for the Microtune MT2131 tuner. 8VSB mode has been 
tested but QAM support will likely require more register work. Hauppauge 
have not announced any QAM devices using the MT2131 so QAM remains 
undone.

For legal reasons, Microtune allowed us to write a GPL driver providing 
we did not document in significant detail any of the registers. This 
explains the lack of comments or defined on register names.

Trent Piepho 4ce1567892 V4L/DVB (5777): Dvb-pll digitv dvb-usb: Eliminate last user of dvb_pll_configure
The last user of dvb_pll_configure was the dvb-usb function
dvb_usb_tuner_calc_regs(), which was nothing more than a wrapper around
dvb_pll_configure().  It's just a copy of the functionality provided by
the tuner_ops calc_regs method, and can be deleted.

There were two users of dvb_usb_tuner_calc_regs().
One was dvb_usb_tuner_set_params_i2c(), which is converted to use
fe->ops.tuner_ops.calc_regs().

The other was the digitv driver.  This driver can use one of two demods,
mt352 or nxt6000.  

For the mt352, the driver would set tuner_ops.calc_regs to 
dvb_usb_tuner_calc_regs().  

We can just attach dvb_pll and use the tuner_ops.calc_regs() provided by 
that module. For the nxt600, the driver would set tuner_ops.set_params 
to digitv_nxt6000_tuner_set_params.  

That function would in turn use dvb_usb_tuner_calc_regs().

We convert it to use tuner_ops.calc_regs() instead, and use 
dvb_pll_attach.

The digitv_tuner_attach() needs to know which frontend was attached by 
digitv_frontend_attach(), since the nxt6000 needs tuner_ops.set_params() 
to be overridden with digitv_nxt6000_tuner_set_params().

So, to do this a digitv_state that says which frontend was used is added 
to the dvb_usb_device private state field.

Trent Piepho b7754d74d2 V4L/DVB (5636): Integrate all users of the fmd1216 tuner with dvb-pll
Enhance the dvb-pll definition of the fmd1216 tuner by adding an init sequence
and a sleep sequence.

The init sequence sets the AGC control register to 0xa0, selecting the fast
time constant and 112 dBuV take-over point.  This the recommended value for
DVB-T operation.

The sleep sequence sets bit P4 (which is believed to turn the analog
demodulator on), turns off the tuning voltage, and sets the AGC control
register to 0x60 (external AGC voltage, the recommended value for analog
operation).

The existing dvb-pll users in the cx88 driver, listed below, will gain these
init and sleep sequences.

CX88_BOARD_HAUPPAUGE_HVR1100    Hauppauge WinTV-HVR1100 DVB-T/Hybrid
CX88_BOARD_HAUPPAUGE_HVR1100LP  Hauppauge WinTV-HVR1100 DVB-T/Hybrid (Low Profi
CX88_BOARD_WINFAST_DTV2000H     WinFast DTV2000 H
CX88_BOARD_HAUPPAUGE_HVR3000    Hauppauge WinTV-HVR3000 TriMode Analog/DVB-S/DV
CX88_BOARD_HAUPPAUGE_HVR1300    Hauppauge WinTV-HVR1300 DVB-T/Hybrid MPEG Encod

This non-dvb-pll user in the cx88 driver should only gain the sleep sequence,
as it already had an equivalent init sequence.  The non-dvb-pll code for this
user is removed.

X88_BOARD_DNTV_LIVE_DVB_T_PRO   digitalnow DNTV Live! DVB-T Pro

In these saa7134 driver, these non-dvb-pll users are converted to use dvb-pll:

SAA7134_BOARD_MD7134                    Medion 7134
SAA7134_BOARD_ASUS_EUROPA2_HYBRID       Asus Europa2 OEM

The saa7134 functions philips_fmd1216_tuner_init(),
philips_fmd1216_tuner_sleep(), and philips_fmd1216_tuner_set_params() are
deleted and the dvb-pll versions are used.

This should result in equivalent sleep, init, and tuning sequences being sent
to the tuner.

For the cxusb driver, only one board is effected:

USB_PID_MEDION_MD95700          	Medion MD95700

This board used dvb_usb_tuner_init_i2c() and dvb_usb_tuner_set_params_i2c()
for init and tuning, respectively.  These functions are effectively the same
as the dvb-pll versions.  They call a tuner pass control function defined at
the dvb-usb level, but this does not matter, as this card does not have a
tuner pass control function (only the dib3000mb does).  This board will gain
the sleep sequence, while init and tuning should be unchanged.

David Brownell 2096b956d2 i2c: Shrink struct i2c_client
This shrinks the size of "struct i2c_client" by 40 bytes:

 - Substantially shrinks the string used to identify the chip type
 - The "flags" don't need to be so big
 - Removes some internal padding

It also adds kerneldoc for that struct, explaining how "name" is really a
chip type identifier; it's otherwise potentially confusing.

Because the I2C_NAME_SIZE symbol was abused for both i2c_client.name
and for i2c_adapter.name, this needed to affect i2c_adapter too.  The
adapters which used that symbol now use the more-obviously-correct
idiom of taking the size of that field.

avoid wasting space in padding.

Trent Piepho d519dcf61e V4L/DVB (5457): Dvb-pll: Replace sleep function with a more capable one
The dvb-pll sleep function could only send a 2-byte sequence to the PLL.
This isn't enough in some cases, for example fmd1216me will need to send
a 4-byte command to set both BB and AB to the correct values.

Instead of using a fake band with a frequency of 0 to store the sleep
data (which has room for only two bytes), the new sleep function works
like the init function.  A new pointer is added to the pll description,
and when non-NULL points to a buffer with the length and data to send.

Trent Piepho df78cb0a18 V4L/DVB (5456): Dvb-pll: Move IF frequency from per-band data to per-tuner data
The IF frequency was specified for each band, but it's not something that
changes from band to band.  None of the tuner definitions had a different
IF frequency (called offset) from one band to another.

Trent Piepho 0fd17d6da8 V4L/DVB (5455): Dvb-pll: Adjust rounding to be consistent
Some PLLs had one half the step size added to the offset, so that the
divisor would be rounded to the nearest integer.  Some didn't and so
would always be rounded down.

This makes dvb-pll round to the nearest when calculating the divisor,
without the offset needing to be fudged.  PLLs that had a fudged offset
have the offset changed to be just the IF frequency.
The satellite PLL dvb_pll_philips_sd1878_tda8261 was rounding up for some
reason, and I've kept it that way.

In addition, frequencies that were rounded to the nearest kHz are
extended to full Hz resolution.  One sixth MHz step sizes that were
listed as 166,666 Hz are changed to 166,667 Hz, which is slightly closer.

PLLs that were already rounding:
dvb_pll_tda665x, offset was 36 1/6 (to nearest kHz) + step/2
dvb_pll_fmd1216me, offset was 36 1/8 (to two digits) + step/2
dvb_pll_thomson_fe6600, offset was 36 1/8 (to two digits) + step/2
dvb_pll_env57h1xd5, offset was 36 1/8 + step

Note that the last PLL, dvb_pll_env57h1xd5, appears to have had a bug in
the offset.  Rather than adding stepsize/2, it was adding a full
stepsize.  The PLL definition originally came from the dibusb driver,
which used 36 1/8 + step/2.  The change to 36 1/8 + step was probably a
mistake added when the tuner was converted to dvb-pll.

Trent Piepho d9e54324d0 V4L/DVB (5374): Or51132: refactor i2c code, improve error resilience
The code the i2c transactions was leftover from the old V4L-based ATSC
driver.  It did too little with too much code.  It is re-written to
remove unnecessary parameters and be more efficient.  A demod register
can now be read with one function call, instead of repeating a dozen line
block of code each time.

There were msleep()'s, which appear to be unnecessary, spread around all
the I2C transactions.  These have been removed.  Reading SNR used to take
about 130 ms, now it's down to 1.8 ms.

Reads from the demodulator's registers do not return correct results
sometimes.  Adding or removing the delays in the I2C transactions did not
appear to effect the probability of failure.  If anything, the
transactions without delays were less likely to fail, but since far more
transactions could be made per second the number of failures per hour was
greater.

To increase reliability, the SNR and get_params functions will now retry
once if they get bad data back.  This appears to have reduced the
probability of failure to effectively zero.
Some error messages are cleaned up or given KERN_* levels when they were
missing.  

or51132_setmode() wasn't returning correct error codes, which is fixed as
well.

Trent Piepho 6bdcc6e6db V4L/DVB (5363): Dvb: Remove lgh06xf driver
The code of the dvb-pll driver and the lgh06xf driver is nearly
identical.  The main difference is that the lgh06xf driver would set the
AGC TOP value on every tune call.  The dvb-pll driver now has the ability
to set the AGC TOP when the front-end device is opened, which is a better
way to go about it.  By using this ability of dvb-pll, the lgh06xf driver
is made unnecessary.

There is one other difference.  dvb-pll will probe for the presence of an
I2C pll chip by doing a one byte read, the lgh06xf driver did not do
this.  In some devices the PLL is not reachable over I2C at the timer the
tuner is attached.  Some more initialization, such as firmware loading,
must take place first.  None of the devices using a LG-H06xF should have
this problem.

Trent Piepho 26aed92289 V4L/DVB (5362): Dvb-pll: add code for doing tuner initialization
Some tuners need or benefit from initialization, to change certain
settings from their power on default values.

Typically, tuners with TUA603x PLLs can benefit from setting the AGC TOP
value to something else.  This patch includes code to set the AGC TOP to
103 dBuV for the Thomson DTT-761x tuners, which I have experimentally
verified gives the best SNR readings, increasing SNR by about 0.19 dB
over the default value.

Other tuners can make use of this as well.  For example, the separate LG
TDVS-H06xF driver's only difference from dvb-pll is this same setting of
AGC TOP value.

Trent Piepho 9ab1ba38e6 V4L/DVB (5361): Dvb-pll: Fix Kconfig files and allow dvb-pll to be optional
A number of drivers selected DVB_PLL when they did not need it, and some
that did need it did not select it.

The DVB_PLL option is given a name and help text, so that it will show up
in the config menu.  DVB_PLL support can be turned on if an out-of-tree
driver needs it.

The standard dvb fe customization support is added to dvb-pll.h.  Since
all modules which select DVB_PLL do so unconditionally, it is not
possible to turn dvb-pll off when an enabled module selects it, unlike
most of the other frontend/tuner drivers.  This is because the users of
dvb-pll have static references to dvb-pll symbols other than the attach
function.  If these references are removed, then dvb-pll will be
disablable as the other frontend/tuner drivers are.
