Antti Palosaari e53c47445b [media] af9033: wrap DVBv3 BER to DVBv5 BER
DVBv5 BER is calculated anyway, so just return it for legacy
read_ber() API too.

Antti Palosaari 83f1161911 [media] af9033: implement DVBv5 statistics for signal strength
Let the demod firmware estimate RF signal strength and return it
to the app as a dBm. To handle that, use thread which reads signal
strengths from firmware in 2 sec intervals when device is active.

Antti Palosaari 6a087f1f6b [media] af9033: clean up logging
It uses I2C client so logging system prints module name
automatically. Function name is also added automatically, if it is
requested from dynamic debug by setting proper format.
Because of that, we could simplify logging in our driver.

Antti Palosaari ca681fe0bc [media] af9033: provide dyn0_clk clock source
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.

Add a variable to keep track if firmware is loaded or not and skip parts of the
initialization if fw is already loaded. Resume from sleep with a different
command compared to initial power up and run command 85 after resume command.
This behaviour is observed when using manufacturer provided binary-only si2168

Antti Palosaari 9dc0f3fe3f [media] af9033: feed clock to RF tuner
IT9135 RF tuner clock is coming from demodulator. We need enable it
early in demod init, before any tuner I/O. Currently it is enabled
by tuner driver itself, but it is too late and performance will be
reduced as some registers are not updated correctly. Clock is
disabled automatically when demod is put onto sleep.

Olli Salonen 868736ad34 [media] sp2: Add I2C driver for CIMaX SP2 common interface module
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).

Olli Salonen 389ce3984b [media] si2168: add ts_mode setting and move to si2168_init
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.
Patches for these modules later in this patch series.

Heinrich Schuchardt 18d75a09e9 [media] media: dib9000: avoid out of bound access
This updated patch also fixes out of bound access to b[].

In dib9000_risc_apb_access_write() an out of bound access to mb[].

The current test to avoid out of bound access to mb[] is insufficient.
For len = 19 non-existent mb[10] will be accessed.

For odd values of len b[] is accessed out of bounds.

For large values of len an of bound access to mb[] may occur in
dib9000_mbx_send_attr.

Mauro Carvalho Chehab 3926d91a6b [media] dib7000p: Callibrate signal strength
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.

Mauro Carvalho Chehab 041ad44968 [media] dib7000p: Add DVBv5 stats support
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.

Mauro Carvalho Chehab b9bc7d59b7 [media] dib8000: rename dib8000_attach to dib8000_init
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.

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

Mauro Carvalho Chehab ed97a6fe53 [media] af9033: Don't export functions for the hardware filter
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.
