[ Upstream commit 380a6c86457573aa42d27ae11e025eb25941a0b7 ]
On faster CPUs a delay is required after the resume command and the restart command. Without the delay, the restart command often returns -EREMOTEIO and the Si2168 does not restart.
Note that this patch fixes the same issue as https://patchwork.linuxtv.org/patch/44304/, but I believe my udelay() fix addresses the actual problem.

commit b9c97c67fd19262c002d94ced2bfb513083e161e upstream.
If m88d3103 chip ID is not recognized, the device is not initialized.
However, it returns from probe without any error, causing this OOPS:

commit 81742be14b6a90c9fd0ff6eb4218bdf696ad8e46 upstream.
Before this patch, when compiled for arm32, the signal strength
were reported as:
Lock (0x1f) Signal= 4294908.66dBm C/N= 12.79dB
Because of a 32 bit integer overflow. After it, it is properly
reported as:
Lock (0x1f) Signal= -58.64dBm C/N= 12.79dB

commit 505a0ea706fc1db4381baa6c6bd2e596e730a55e upstream.
With the current settings, only one channel locks properly.
That's likely because, when this driver was written, Brazil
were still using experimental transmissions.
Change it to reproduce the settings used by the newer drivers.
That makes it lock on other channels.
Tested with both PixelView SBTVD Hybrid (cx231xx-based) and
C3Tech Digital Duo HDTV/SDTV (em28xx-based) devices.

commit dafb65fb98d85d8e78405e82c83e81975e5d5480 upstream.
On this frontend, it takes a while to start output normal
TS data. That only happens on state S9. On S8, the TS output
is enabled, but it is not reliable enough.
However, the zigzag loop is too fast to let it sync.
As, on practical tests, the zigzag software loop doesn't
seem to be helping, but just slowing down the tuning, let's
switch to hardware algorithm, as the tuners used on such
devices are capable of work with frequency drifts without
any help from software.

commit e8beb02343e7582980c6705816cd957cf4f74c7a upstream.
The tda1004x was updating the properties cache before locking.
If the device is not locked, the data at the registers are just
random values with no real meaning.
This caused the driver to fail with libdvbv5, as such library
calls GET_PROPERTY from time to time, in order to return the
DVB stats.

Device stopped to tuning some channels after regmap conversion.
Reason is that regmap_update_bits() works a bit differently for
partially volatile registers than old homemade routine. Return
back to old routine in order to fix issue.

The dvb_frontend.c core defines a FE_ALGO_HW symbol that it is
never used. Also, both cx24123 returns 1 to get_algo() callback
instead of using DVBFE_ALGO_HW.
Probably, those are some left overs from some code cleanup.
Let's stop returning magic numbers and use the proper macro
value.

The B2100A dvb NIM card from ST has 2x stv0367 demodulators
and 2x TDA18212 silicon tuners, with a 16Mhz crystal. To
get this working properly with the upstream driver we need
to add support for the 16Mhz reference clock.

When using stv0367 demodulator with STi STB platforms,
we can have easily have four or more stv0367 demods running
in the system at one time.
As typically the b2120 reference design ships with a b2004a daughter
board, which can accept two dvb NIM cards, and each b2100A NIM
has 2x stv0367 demods and 2x NXPs tuner on it.
In such circumstances it is useful to print the i2c address
on error messages to know which one is failing due to I2C issues.

The Linux stack is short; we need to be able to count the number
of bytes used at stack on each function. So, we don't like to
use variable-length arrays, as complained by smatch:
drivers/media/dvb-frontends/horus3a.c:57:19: warning: Variable length array is used.
The max usecase of the driver seems to be 10 bytes + 1 for the
register.
So, let's be safe and allocate 11 bytes for the write buffer.
This should be enough to cover all cases. If not, let's print
an error message.
