This moves the I2C debug dump into the preceding dev_dbg() call by
utilising the %*ph format macro and removes the call to
print_hex_debug_bytes().

Doing the I2C read operation with two calls to i2c_transfer() causes the
exclusive I2C bus lock of the underlying adapter to be released. While this
isn't an issue if only one demodulator is attached to the bus, having two
or even more causes troubles in that concurrent accesses to the different
demods will cause all kinds of issues due to wrong data being returned on
read operations (for example, the TS config register will be set wrong).
This changes the read_regs() function to do the operation in one go (by
calling i2c_transfer with the whole msg list instead of one by one) to not
loose the I2C bus lock, fixing all sorts of random runtime failures.

Do unfreeze_regs() directly when accessing the demod registers is done,
and don't have multiple unfreeze's on different conditions, which even
can get prone to errors.

Those demods are programmed in the same way as the CXD2841ER/54ER and can
be handled by this driver. Support added in a way matching the existing
code, supported delivery systems are set according to what each demod
supports.
Updates the type string setting used for printing the "attaching..." log
line aswell.

From: Daniel Scheller <d.scheller@gmx.net>
The way the MAKE_IFFREQ_CONFIG macros are written make it impossible to
pass regular integers for iffreq calculation, since this will cause "SSE
register return with SSE disabled" compile errors. This changes the
calculation into C functions which also might help when debugging. Also,
expand all passed frequencies from MHz to Hz scale.

From: Daniel Scheller <d.scheller@gmx.net>
Throughout the patch series some configuration flags will be added to the
demod driver. This patch prepares this by adding the flags var to
struct cxd2841er_config, which will serve as a bitmask to toggle various
options and behaviour in the driver.

From: Daniel Scheller <d.scheller@gmx.net>
Some cards/bridges wrap i2c_gate_ctrl handling with a mutex_lock(). This is
e.g. done in ddbridge to protect against concurrent tuner access with
regards to the dual tuner HW, where concurrent tuner reconfiguration can
result in tuning fails or bad reception quality. When the tuner driver
additionally tries to open the I2C gate (which e.g. the tda18212 driver
does) when the demod already did this, this will lead to a deadlock. This
makes the calls to i2c_gatectrl from the demod driver optional when the
flag is set, leaving this to the tuner driver. For readability reasons and
to not have the check duplicated multiple times, the setup is factored
into cxd2841er_tuner_set().
This commit also updates the netup card driver (which seems to be the only
consumer of the cxd2841er as of now).

Add a AUTO_IFHZ flag and a function that will read IF speed values from any
attached tuner if the tuner supports this and if AUTO_IFHZ is enabled, and
else the passed default value (which probably matches Sony ASCOT tuners)
will be passed back. The returned value is then used to calculate the iffeq
which the demod will be programmed with.

The Sony CXD28xx demods may have other tuner types attached to them (e.g.
NXP TDA18212), so don't mandatorily configure and enable the ASCOT
functionality, but make this conditional by a config flag.

From: Daniel Scheller <d.scheller@gmx.net>
When AUTO_IFHZ is set and the tuner is supposed to provide proper IF speed
values, it should be possible to have the tuner setup take place before
the demod is configured, else the demod might be configured with either
wrong (old), or even no values at all, which obviously will cause issues.
To set this behaviour in the most flexible way, this is done with a
separate flag instead of making this depend on AUTO_IFHZ.
It should be evaluated if tuning shouldn't take place earlier in all cases
and hardware constellations.

Don't wait for FE_HAS_LOCK in set_frontend_tc() and thus don't hammer the
lock status register with inquiries when CXD2841ER_NO_WAIT_LOCK is set
in the configuration, which also unneccessarily blocks applications until
a TS LOCK has been acquired. Rather, API and applications will check for
a TS LOCK by utilising the tune fe_op, read_status and get_frontend ops,
which is sufficient.

Bits 3 and 4 of the TSCONFIG register are important for certain hardware
constellations, in that they need to be zeroed. Add a configuration flag
to toggle this.

On DVB-T/T2 at least, SNR might be reported as >2500dB, which not only is
just wrong but also ridiculous, so fix this by improving the conversion
of the register value.
The INTLOG10X100 function/macro and the way the values are converted were
both taken from DD's cxd2843 driver.

This is a backport of the board control setup from the vendor provided
dddvb driver package, which does additional device initialisation based
on the board_control device info values. Also backports the TS quirk
flags which is used to control setup and usage of the tuner modules
soldered on the bridge cards (e.g. CineCTv7, CineS2 V7, MaxA8 and the
likes).
Functionality originates from ddbridge vendor driver. Permission for
reuse and kernel inclusion was formally granted by Ralph Metzler
<rjkm@metzlerbros.de>.

From: Daniel Scheller <d.scheller@gmx.net>
Some Flex modules (mostly with anyof C/C2/T/T2 demods based on the Sony
CXD28xxER series) are equipped with an interface named XO2 (which
appears to be the Lattice MachXO2). Add functionality to detect such
links and initialise them, so any tuner module with such an interface can
be used.
This also adds dummy detection for any possible connected module, telling
the user it isn't supported at this very moment.
Also adds i2c_io(), i2c_write() and i2c_write_reg(), all required for the
XO2 handling functionality.

Properly detect and attach Ports and Flex modules with the Sony CXD28xxER
series demods. This makes newer Cine cards and most DuoFlex C/C2/T/T2 (or
any combination of these systems) work, PCI IDs need to be added though.
Note: This utilises the CXD2841ER demod driver, which requires the changes
from this patch series to properly work. Without those changes, it won't
function properly (if at all).

From: Daniel Scheller <d.scheller@gmx.net>
Adds hardware IDs for all Sony CXD-based Cine-cards and MaxA8 devices, also
adds some other yet missing IDs like the Octopus V3, Octopus OEM and
Octopus Mini, as well as cards with unknown/deleted sub-ids.
