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

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.

[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.

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.

[media] v4l: atmel-isi: remove SOF wait in start_streaming()
when a userspace applications calls the VIDIOC_STREAMON ioctl. The
V4L2 core calls the soc_camera_streamon function, which is responsible
for starting the video stream. It does so by first starting the atmel-isi
host by a call to the vb2_streamon function, and then starting the sensor
by a call to the video.s_stream sensor subdev operation.
That means we wait for a SOF in start_streaming() before call sensor's
s_stream(). It is possible no VSYNC interrupt arrive as the sensor
hasn't been started yet.
To avoid such case, this patch remove the code to wait for the VSYNC
interrupt. And such code is not necessary.

When a fatal error that prevents any further video streaming occurs in a

[media] v4l: omap4iss: Reset the ISS when the pipeline can't be stopped
When a failure to stop a module in the pipeline is detected, the only
way to recover is to reset the ISS. However, as other users can be using
a different pipeline with other modules, the ISS can't be reset
synchronously with the error detection.
Keep track of modules that have failed to stop, and reset the ISS
accordingly when the last user releases the last reference to the ISS.
Refuse to start streaming on a pipeline that contains a crashed module,
as the hardware wouldn't work anyway.
Modify the omap4iss_pipeline_set_stream() function to record the new ISS
pipeline state only when no error occurs, except when stopping the
pipeline in which case the pipeline is still marked as stopped.
