The Silicon Labs Si2146 tuner seems to work with the same driver as the Si2157,
but there a few exceptions. The powerup command seems to be quite a bit
different. In addition there's a property 0207 that requires a different value.
Thus another entry is created in the si2157_id table to support also si2146 in
this driver.

IT913x tuner driver disables own clock, provided by demod core, as
very a first operation when tuner is put on *sleep*. That likely
causes failure of all the rest commands on sleep sequence, which
leads situation where tuner is not actually on sleep, but consuming
a lot of power.
I measured 102mA current consumption from the USB before change
and after change it was only 32mA. Used device was single tuner
IT9135 BX.
Second reason to remove that register from tuner driver is reason
it is simply on wrong driver (demod vs. tuner), breaking the
principle of correct driver.
Clock is now provided more correctly af9033 demod driver as a
config option.

Instead of sending command 13 to the tuner, send command 16 when sleeping. This
behaviour is observed when using manufacturer provided binary-only Linux driver
for TechnoTrend CT2-4400 (Windows driver does not do power management).
The issue with command 13 is that firmware loading is necessary after that.
This is not an issue with tuners that do not require firmware, but starting
streaming after sleep on an Si2158 takes noticeable time as firmware is

Instead of using if (foo == false), just use
if (!foo).

Maximum satellite symbol rate used is 45000000Sps which overflows
when multiplied by 135. As final calculation result is fraction,
we could use mult_frac macro in order to keep calculation inside
32 bit number limits and prevent overflow.
Original bug and fix was provided by Nibble Max. I decided to
implement it differently as it is now.

Same thing for si2157 as Antti did earlier for tda18212:
There is no need to print module name nor function name as those
are done by kernel logging system when dev_xxx logging is used and
driver is proper I2C driver.
While here, fix a typo ("unknown") in si2157_init.

Now that xc5000_set_params() is also called during resume,
move the code that checks for the firmware to happen there.
This way, the firmware will be loaded either for analog or
digital TV when .resume callback is called.

xc5000_set_params() is a bad name for a function that
handles only digital TV. Rename it to xc5000_set_digital_params(),
and proper name the generic function that works for both
digital and analog.
No functional changes.

As we need a function that reapply the last tuned radio,
in order to do resume, split the code that validates and
updates the internal priv struct from the ones that
actually set radio and TV.
A latter patch will add support for resume.

After xc5000 stops working, it waits for 5 seconds, waiting
for a new usage. Only after that it goes to low power mode.
If a suspend event happens before that, a work queue will
remain active, with causes suspend to crash.

Currently, firmware retry logic keeps reading from FS every
time during the retry logic. This is not needed. Instead,
only release the firmware read after success.
While here, make the non-debug messages less verbose, as it
only matters to the user if the firmware was successfully
loaded, or if some error happened.

With the current code, if something bad happens during the
firmware init process, the device will keep trying forever,
and removing it would cause an OOPS.
Instead, try only a limited amount of time. If not, fails.

The programmed frequency on xc4000 is not the middle
frequency, but the initial frequency on the bandwidth range.
However, the DVB API works with the middle frequency.
This works fine on set_frontend, as the device calculates
the needed offset. However, at get_frequency(), the returned
value is the initial frequency. That's generally not a big
problem on most drivers, however, starting with changeset
6fe1099c7a, the frequency drift is taken into account at
dib7000p driver.
This broke support for PCTV 340e, with uses dib7000p demod and
xc4000 tuner.

As reported by Kbuildtest:
warning: (VIDEO_PVRUSB2 && VIDEO_TLG2300 && VIDEO_USBVISION && VIDEO_GO7007 && VIDEO_AU0828_V4L2 && VIDEO_CX231XX && VIDEO_TM6000 && VIDEO_EM28XX && VIDEO_IVTV && VIDEO_MXB && VIDEO_CX18 && VIDEO_CX23885 && VIDEO_CX88 && VIDEO_BT848 && VIDEO_SAA7134 && VIDEO_SAA7164) selects VIDEO_TUNER which has unmet direct dependencies (MEDIA_SUPPORT && MEDIA_TUNER)
That happens when:
# CONFIG_MEDIA_ANALOG_TV_SUPPORT is not set
CONFIG_MEDIA_DIGITAL_TV_SUPPORT=y
# CONFIG_MEDIA_RADIO_SUPPORT is not set
# CONFIG_MEDIA_SDR_SUPPORT is not set
CONFIG_VIDEO_AU0828_V4L2=y
CONFIG_VIDEO_CX231XX=y
CONFIG_VIDEO_TM6000=y
CONFIG_VIDEO_EM28XX=y
CONFIG_VIDEO_TUNER=y
CONFIG_MEDIA_SUPPORT=y
With means that we need to enable MEDIA_TUNER also when DTV
is enabled. While the above config doesn't cover, if we enable
SDR, the same error can also happen.

Some drivers, like au0828 are very sensitive to tuner sleep and may
break if the sleep happens too fast. Also, by keeping the tuner alive
for a while could speedup tuning process during channel scan. So,
change the logic to delay the actual sleep to 5 seconds after its
command.
