      [media] media: mx1_camera: Remove driver · 90b05589
      Alexander Shiyan authored 
      That driver hasn't been really maintained for a long time. It doesn't
compile in any way, it includes non-existent headers, has no users,
and marked as "BROKEN" more than year. Due to these factors, mx1_camera
is now removed from the tree.

      [media] rcar_vin: copy flags from pdata · 25dfa02c
      Ben Dooks authored 
      The platform data is a single word, so simply copy
it into the device's private data structure than
keeping a copy of the pointer.

This will make changing to device-tree binding
easier as it is one allocation instead of two.

      [media] V4L: soc-camera: explicitly free allocated managed memory on error · 057c2a2e
      Guennadi Liakhovetski authored 
      devm_kzalloc() allocations are freed when the device is unbound. But if a
certain path fails and the allocated memory cannot be used anyway it is
better to free it explicitly immediately. This patch does exactly this if
asynchronous group probing in scan_async_group() fails after memory has
been allocated.

      [media] dib7000p: Callibrate signal strength · 3926d91a
      Mauro Carvalho Chehab authored 
      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.

      [media] dib7000p: Add DVBv5 stats support · 041ad449
      Mauro Carvalho Chehab authored 
      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.

      [media] dib8000: export just one symbol · d44913c1
      Mauro Carvalho Chehab authored 
      Exporting multiple symbols don't work as it causes compilation
breakages, due to the way dvb_attach() works.

The bug happens when:
        CONFIG_DVB_DIB8000=m
	CONFIG_DVB_USB_DIB0700=y

As a bonus, dib8000 won't be loaded anymore if the device uses
a different frontend, reducing the memory footprint.

Tested with both Pixelview PV-D231 and MyGica S870.

      [media] dib8000: rename dib8000_attach to dib8000_init · b9bc7d59
      Mauro Carvalho Chehab authored 
      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 multiple symbols don't work as it causes compilation
breakages, due to the way dvb_attach() works.

This were reported several times, like:

   drivers/built-in.o: In function `cxusb_dualdig4_rev2_tuner_attach':
>> cxusb.c:(.text+0x27d4b5): undefined reference to `dib7000p_get_i2c_master'
   drivers/built-in.o: In function `dib7070_set_param_override':
   cxusb.c:(.text+0x27d5a5): undefined reference to `dib0070_wbd_offset'
>> cxusb.c:(.text+0x27d5be): undefined reference to `dib7000p_set_wbd_ref'
   drivers/built-in.o: In function `dib7070_tuner_reset':
>> cxusb.c:(.text+0x27d5f9): undefined reference to `dib7000p_set_gpio'
   drivers/built-in.o: In function `cxusb_dualdig4_rev2_frontend_attach':
>> cxusb.c:(.text+0x27df5c): undefined reference to `dib7000p_i2c_enumeration'

In this specific report:
	CONFIG_DVB_USB_CXUSB=y
	CONFIG_DVB_DIB7000P=m

But the same type of bug can happen if:
	CONFIG_DVB_DIB7000P=m
and one of the bridge drivers is compiled builtin (cxusb, cx23885-dvb
and/or dib0700).

As a bonus, dib7000p won't be loaded anymore if the device uses
a different frontend, reducing the memory footprint.

Tested with Hauppauge Nova-TD (2 frontends).

However, the dib7000p initialization can require up to 3
functions to be called:
	- dib7000p_get_i2c_master;
	- dib7000p_i2c_enumeration;
	- dib7000p_init (before this patch dib7000_attach).

(plus a bunch of other functions that the bridge driver will
need to call).

So, let's rename the function that probes and init the hardware
to dib7000p_init.

A latter patch will add a new dib7000p_attach that will be
used as originally conceived by dvb_attach() way.
