[media] tc358743: set direction of reset gpio using devm_gpiod_get
Commit 256148246852 ("[media] tc358743: support probe from device tree")
failed to explicitly set the direction of the reset gpio. Use the
optional flag of devm_gpiod_get to make up leeway.
This is also necessary because the flag parameter will become mandatory
soon.
Most of the parameters here are already well defined at
the userspace documentation. Yet, it is good to add some
documentation, for the developers to be sure that they
are the same as the ones at userspace API.

The dvb_frontend.c core defines a FE_ALGO_HW symbol that it is

2) struct vb2_queue has a number of private elements that are

The driver creates one LinuxDVB adapter, and a
demux/dvr/frontend set of devices for each tsin channel
which is specificed in the DT. It has been tested with
multiple tsin channels tuned, locked, and grabbing TS
simultaneously.

[media] stv0367: Add support for 16Mhz reference clock
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.

[media] stv0367: Refine i2c error trace to include i2c address
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.

Commit 275ddb40bcf686d210d86c6718e42425a6a0bc76 removed the lirc
"protocol" but kept backwards compatibility by always listing
the protocol as present and enabled. This patch further improves
the logic by only listing the protocol if the lirc module is loaded
(or if lirc is builtin).
