Original plan was to implement driver as one file per used demod
standard (mn88472_c.c, mn88472_t.c and mn88472_t2.c). However, that
plan was a mistake as driver code differences are so small between
different standards. Due to that rename this file and implement all
the needed functionality to that file.

M88RS6000 is the integrated chip, which includes tuner and demod. Its
internal demod is similar with M88DS3103 except some registers
definition.
The main different part of this internal demod from others is its
clock/pll generation IP block sitting inside the tuner die. So clock/pll
functions should be configed through its tuner i2c bus, NOT its demod
i2c bus.
The demod of M88RS6000 need the firmware: dvb-demod-m88rs6000.fw

This code is needlessly complicated and checkpatch.pl complains that we
go over the 80 characters per line limit.
If we flip the "if (!lock) {" test to "if (lock) return;" then we can
remove an indent level from the rest of the function.
We can add two returns in the "if (state->srate >= 10000000) {"
condition and move the else statement back an additional indent level.
There is another "if (!lock) {" check which can be removed since we have
already checked "lock" and know it is zero at this point. This second
check on "lock" is also a problem because it sets off a static checker
warning. I have reviewed this code for some time to see if something
else was intended, but have concluded that it was simply an oversight
and should be removed. Removing this duplicative check gains us an

This patch partially reverts 0fb220f2a5. What happened is
that the conversion of debug messages to use pr_debug() was a

enable debug level via a modprobe parameter, and then to
enable the dynamic printk's.
So, for now, let's use printk() directly at dprintk().

This patch adds driver for tc90522 demodulator chips.
The chip contains 4 demod modules that run in parallel and are independently
controllable via separate I2C addresses.
Two of the modules are for ISDB-T and the rest for ISDB-S.
It is used in earthsoft pt3 cards.
Note that this driver does not init the chip,
because the initilization sequence / register setting is not disclosed.
Thus, the driver assumes that the chips are initilized externally
by its parent board driver before fe->ops->init() are called.
Earthsoft PT3 PCIe card, for example, contains the init sequence
in its private memory and provides a command to trigger the sequence.

AF903x/IT913x demod provides clock source(s). It seems that this
clock source is used for integrated RF tuner of IT913x. It is
enabled by default, but firmware disables it automatically when
suspend is requested (suspend_flag (0x004c) + trigger_ofsm
(0x0000)). Automatic disable behavior seems to be similar for both
AF903x and IT913x I tested, though there is no likely any real
clock user in a case of AF903x.

Driver for the CIMaX SP2 common interface chip. It is very much based on
the existing cimax2 driver for cx23885, but should be more reusable. The
product has been sold with name Atmel T90FJR as well and the data sheets
for that chip seem to be publicly available.
It seems that the USB device that I have and the cx23885 based devices will
need to interact differently with the chip for the CAM operations. Thus
there is one callback function that is passed on to the sp2 driver
(see function sp2_ci_op_cam for that one).
IRQ functionality is not included currently (not needed by USB devices
and I don't have a PCIe device for development).

Luis Alves submitted a TS mode patch to si2168 earlier, but the
patch was rejected due to a small issue. Here is a working version.
Also, setting of TS mode is moved from si2168_set_frontend to
si2168_init.
This patch adds the TS mode as a config option for the si2168 demod:
- ts_mode added to config struct.
- Possible (interesting) values are
* Parallel mode = 0x06
* Serial mode = 0x03
Currently the modules using this demod only use parallel mode.

Calibrate the signal strength to dB.
For this callibration, I used adapter 0 (antenna 1), connected
via a normal cable to a DTF-2111 generator.
The same cabling and RF generator connected to adapter 1
(antenna 2) has a difference of +3dBm (signal was stronger
there).
Yet, changing the RF for a difference of, let's say, 6dB
reflected on a 6dB difference at the measured signal, with
is good.
So, the signal strengh can indeed be used to measure the
antenna gain, if the antenna is repositioned. It is
not precise to measure the absolute dBm value, however.

Adds DVBv5 stats support. For now, just mimic whatever dib8000
does, as they're very similar, with regards to statistics.
However, dib7000p_get_time_us() likely require some
adjustments, as I didn't actually reviewed the formula
for it to work with DVB-T. Still, better than nothing,
as latter patches can improve it.
This patch also doesn't show the signal strength in dB
yet. The code is already there, but it requires to be
callibrated.
A latter patch will do the calibration.
It seems that this patch is also a bug fix: Before this
patch, the frontend were not tuning with some userspace
tools. I suspect that dib7000p firmware or hardware
internally expects that the statistics to be collected,
in order for it to work. With this patch, the DVB core
will always retrive statistics, even if userspace doesn't
request. So, it makes the device work on all tested apps.

Well, what we call as "foo_attach" is the method that should
be called by the dvb_attach() macro.
It should be noticed that the name "dvb_attach" is really a
bad name and don't express what it does.
dvb_attach() basically does three things, if the frontend is
compiled as a module:
- It lookups for the module that it is known to have the
given symbol name and requests such module;
- It increments the module usage (anonymously - so lsmod
doesn't print who loaded the module);
- after loading the module, it runs the function associated
with the dynamic symbol.
When compiled as builtin, it just calls the function given to it.
As dvb_attach() increments refcount, it can't be (easily)
called more than once for the same module, or the kernel
will deny to remove the module, because refcount will never
be zeroed.
In other words, the function name given to dvb_attach()
should be one single symbol that will always be called
before any other function on that module to be used.
For almost all DVB frontends, there's just one function,
but, on dib8000, there are several exported symbols.
We need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that
will be the first one to be called, whatever initialization
is needed.
So, let's rename this function, in order to prepare for
a next patch that will add a new attach() function that
will be the only one exported by this module.

Exporting functions for hardware filter is a bad idea, as it
breaks compilation if:
CONFIG_DVB_USB_AF9035=y
CONFIG_DVB_AF9033=m
Because the PID filter function calls would be hardcoded at
af9035.
The same doesn't happen with af9033_attach() because the
dvb_attach() doesn't hardcode it. Instead, it dynamically
links it at runtime.
However, calling dvb_attach() multiple times is problematic,
as it increments module kref.
So, the better is to pass one parameter for the af9033 module
to fill the hardware filters, and then use it inside af9035.

There are large chunks of code at drx-j that aren't used. Most
of them are due to analog TV support. Well, just enabling them
won't make analog support work, as devices with DRX and analog
support requires an extra chip (avf4910).
We don't have drivers for it, nor the current device that uses
this frontend has support for analog TV.
So, let's just get rid of this code. If latter needed, this
patch can easily be reverted from git history.

Add m88rs2000_get_tune_settings, min delay of 2000 ms on symbol
rate more than 3000000 and delay of 3000ms less than this.
Adding min delay prevents crashing the frontend on continuous
transponder scans. Other dvb_frontend_tune_settings remain as default.
This makes very little time difference to good channel scans, but slows down
the set frontend where lock can never be achieved i.e. DVB-S2.

Use multiple linear segments to better interpolate the dBm
for the signal strength.
The table that converts from linear strength to dB was
empirically determinated with the help of a signal generator
(DTA-2111).
The entries from -35dBm to -22.5dBm were taken using just
the signal generator and the board.
For the entries from -36dBm to -51dBm, a 16 dB tap was used,
in order to extend its range.
Signals below to -51dBm are just linearly interpolated.

Better to have Signal strength in dB.
This takes a very rough estimation for the signal strength,
that was calibrated using a Dektec DTA-2111 Gold RF generator
and a Pixelview dib8076 stick.
It estimates the signal strength using a linear equation where:
- the max is -22.5 dBm, with returns 55953
- the min is -35.0 dBm, with returns 50110
With -22dBm, the signal strengh is returned as 65535.
Unfortunately, the min strength generated with DTA-2111 is
-35dBm.
It should be noticed that approximating it by a linear equation
is not right. I should probably be splitting it into 0.5 dB
linear segments, in order to get a higher precision, just like
it is done on mb86a20s, but that would force me to add some
attenuators, in order to get dB levels below -35dBm, which is,
btw, strong enough to get signal lock.

The advantage of DVBv5 stats is that it allows adding proper
scales to all measures. use it for this frontend.
This patch adds a basic set of stats, basically cloning what's already
provided by DVBv3 API. Latter patches will improve it.

On ISDB-T, the valid values for interleaving are 0, 1, 2 and 4.
While the first 3 are properly reported, the last one is reported
as 3 instead. Fix it.
Tested with a Dektec DTA-2111 RF generator.

The logic that detects if auto search mode should be used is too
complex.
Also, it doesn't cover all cases, as the dib8000_tune logic
requires either auto mode or a fully specified manual mode.
So, move it to a separate function and add some extra debug
data to help identifying when it falled back to auto mode,
because the manual settings are invalid.

Both dvbv5-scan and dvbv5-zap tools call FE_GET_PROPERTY inside the
loop that checks for stats. If the frontend doesn't support DVBv5, it
falls back to call the DVBv5 stats APIs(FE_READ_BER, FE_READ_SIGNAL,
FE_READ_SNR and FE_READ_UNCORRECTED_BLOCKS).
A call to FE_GET_PROPERTY makes dvb-frontend core to call get_frontend().
However, due to a race condition on dib8000 between dib8000_get_frontend
and dib8000_tune, if get_frontend occurs too early, it causes the
tune state machine to fail and not get any lock.
This patch adds a workaround code that makes get_frontend() to just
return if none of the frontends have a SYNC. This change fixed the issue
with dvbv5-scan/dvbv5-zap, but a fine-tuned logic might be needed in
the future, when we implement DVBv5 stats on this frontend.
The procedure to test the bug and the fix is the one below:
1) tune into a non-existing frequency with:
$ dvbv5-zap -I dvbv5 -c non_existing_freqs -m 679142857 -t3
2) tune/lock into an existing frequency with:
$ dvbv5-zap -I dvbv5 -c isdb-test -m 479142857
or
$ dvbv5-scan isdb-test
In this case, 679 MHz carrier doesn't exist. Only 479 MHz does.

As the dvb-frontend kthread can be called anytime, it can race
with some get status ioctl. So, it seems better to avoid one to
race with the other while reading a 32 bits register.
I can't see any other reason for having a mutex there at I2C, except
to provide such kind of protection, as the I2C core already has a
mutex to protect I2C transfers.
Note: instead of this approach, it could eventually remove the dib8000
specific mutex for it, and either group the 4 ops into one xfer or
to manually control the I2C mutex. The main advantage of the current
approach is that the changes are smaller and more puntual.
