0400c5354a [media] dib8000: improve block statistics
PER/UCB statistics are collected once on each 1 second.
However, it doesn't provide the total number of packets
needed to calculate PER.

Yet, as we know the bit rate, it is possible to estimate
such number. So, do it.

7a9d85d555 [media] dib8000: Fix UCB measure with DVBv5 stats
On dib8000, the block error count is a monotonic 32 bits register.
With DVBv5 stats, we use a 64 bits counter, that it is reset
when a new channel is tuned.

Change the UCB counting start from 0 and to be returned with
64 bits, just like the API requests.

42ff76bdb0 [media] dib8000: make a better estimation for dBm
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.

b4600d70c0 [media] dib8000: estimate strength in dBm
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.

6ef06e78c7 [media] dib8000: add DVBv5 stats
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.

ad97618704 [media] dib8000: improves the auto search mode check logic
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.

70315b3eaf [media] dib8000: Don't let tuner hang due to a call to get_frontend()
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.

5ac64ba12a [media] dib8000: make 32 bits read atomic
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.

b4559ace2c [media] ts2020: keep 1.06 MHz as default value for frequency_div
Changeset 9e8da9e8 added a parameter to specify the frequency
divisor, used by the driver. However, not all places are passing
this parameter. So, preserve the previous default, to avoid breaking

03a6727995 [media] media: dvb-frontends: ts2020: Added in a option for frequency divider value for s600 devices
When the tuner part of the ds3000 driver was split to share code with the m88rs2000 driver, the ts2020 driver used
the frequency divider value from the m88rs2000 driver.  However the ds3000 driver requires a different value, and this
resulted in some frequecies being invisible to the tuner.  This patch adds back in the value needed for the ds3000 driver
and configured as an option in the dw2102 frontend driver.
It may also apply to su3000 devices, which use the same ds3000 driver, but for now it is only applied to the s660 device.

6894c070e1 [media] tda10071: change firmware download condition
Reading firmware status register to detect whether firmware is
running or not didn't work 100% reliably. That register was
likely set by firmware itself which means it could not contain
reasonable values until firmware is up and running. Usually it
just worked as some garbage value was returned accidentally but it
appears that in some cases returned garbage value was 0x00 which
was considered "firmware is up and running" by the driver and
firmware loading was skipped leaving device to non-working state.
Fix problem by removing unreliable check and let the driver keep
count whether firmware is loaded or not.

X-Patchwork-Delegate: mchehab@redhat.com
There are a few cases where breaking the code into separate
lines make it worse to read. However, on several places,
breaking it to make checkpatch.pl happier is OK and improves
code readability.
So, break longer lines where that won't cause harm.
