Pull media updates from Mauro Carvalho Chehab:
"Brazil's Independence Day pull request :-)
This is one of the biggest media pull requests, with 625 patches
affecting almost all parts of media (RC, DVB, V4L2, CEC, docs).
This contains:
- A lot of new drivers:
* DVB frontends: mxl5xx, stv0910, stv6111;
* camera flash: as3645a led driver;
* HDMI receiver: adv748X;
* camera sensor: Omnivision 6650 5M driver (ov6650);
* HDMI CEC: ao-cec meson driver;
* V4L2: Qualcom camss driver;
* Remote controller: gpio-ir-tx, pwm-ir-tx and zx-irdec drivers.
- The DDbridge DVB driver got a massive update, with makes it in sync
with modern hardware from that vendor;
- There's an important milestone on this series: the DVB
documentation was written in 2003, but only started to be updated
in 2007. It also used to contain several gaps from the time it was
kept out of tree, mentioning error codes and device nodes that
never existed upstream. On this series, it received a massive
update: all non-deprecated digital TV APIs are now in sync with the
current implementation;
- Some DVB APIs that aren't used by any upstream driver got removed;
- Other parts of the media documentation algo got updated, fixing
some bugs on its PDF output and making it compatible with Sphinx
version 1.6.
As the number of hacks required to build PDF output reduced, I hope
we'll have less troubles as newer versions of our documentation
toolchain are released (famous last words);
- As usual, lots of driver cleanups and improvements"

||||
used in torch mode as well.
|
||||
|
||||
Ranges below noted as [a, b] are closed ranges between a and b, i.e. a
|
||||
and b are included in the range.

By default this is off, but when set to 1 the driver will store the current

CEC Pin framework
|
||||
-----------------
|
||||
|
||||
Most CEC hardware operates on full CEC messages where the software provides
|
||||
the message and the hardware handles the low-level CEC protocol. But some
|
||||
hardware only drives the CEC pin and software has to handle the low-level
|
||||
CEC protocol. The CEC pin framework was created to handle such devices.
|
||||
|
||||
Note that due to the close-to-realtime requirements it can never be guaranteed
|
||||
to work 100%. This framework uses highres timers internally, but if a
|
||||
timer goes off too late by more than 300 microseconds wrong results can
|
||||
occur. In reality it appears to be fairly reliable.
|
||||
|
||||
One advantage of this low-level implementation is that it can be used as
|
||||
a cheap CEC analyser, especially if interrupts can be used to detect
|
||||
CEC pin transitions from low to high or vice versa.

CEC Notifier framework
|
||||
----------------------
|
||||
|
||||
Most drm HDMI implementations have an integrated CEC implementation and no
|
||||
notifier support is needed. But some have independent CEC implementations
|
||||
that have their own driver. This could be an IP block for an SoC or a
|
||||
completely separate chip that deals with the CEC pin. For those cases a
|
||||
drm driver can install a notifier and use the notifier to inform the
|
||||
CEC driver about changes in the physical address.

Tuning into a Digital TV physical channel and starting decoding it
|
||||
requires changing a set of parameters, in order to control the tuner,
|
||||
the demodulator, the Linear Low-noise Amplifier (LNA) and to set the
|
||||
antenna subsystem via Satellite Equipment Control (SEC), on satellite
|
||||
systems. The actual parameters are specific to each particular digital
|
||||
antenna subsystem via Satellite Equipment Control - SEC (on satellite
|
||||
systems). The actual parameters are specific to each particular digital
|
||||
TV standards, and may change as the digital TV specs evolves.
|
||||
|
||||
In the past, the strategy used was to have a union with the parameters
|
||||
needed to tune for DVB-S, DVB-C, DVB-T and ATSC delivery systems grouped
|
||||
there. The problem is that, as the second generation standards appeared,
|
||||
those structs were not big enough to contain the additional parameters.
|
||||
Also, the union didn't have any space left to be expanded without
|
||||
breaking userspace. So, the decision was to deprecate the legacy
|
||||
union/struct based approach, in favor of a properties set approach.
|
||||
In the past (up to DVB API version 3 - DVBv3), the strategy used was to have a
|
||||
union with the parameters needed to tune for DVB-S, DVB-C, DVB-T and
|
||||
ATSC delivery systems grouped there. The problem is that, as the second
|
||||
generation standards appeared, the size of such union was not big
|
||||
enough to group the structs that would be required for those new
|
||||
standards. Also, extending it would break userspace.
|
||||
|
||||
So, the legacy union/struct based approach was deprecated, in favor
|
||||
of a properties set approach. On such approach,
|
||||
:ref:`FE_GET_PROPERTY and FE_SET_PROPERTY <FE_GET_PROPERTY>` are used
|
||||
to setup the frontend and read its status.
|
||||
|
||||
The actual action is determined by a set of dtv_property cmd/data pairs.
|
||||
With one single ioctl, is possible to get/set up to 64 properties.
|
||||
|
||||
This section describes the new and recommended way to set the frontend,
|
||||
with supports all digital TV delivery systems.
|
||||
|
||||
.. note::
|
||||
|
||||
On Linux DVB API version 3, setting a frontend were done via
|
||||
struct :c:type:`dvb_frontend_parameters`.
|
||||
This got replaced on version 5 (also called "S2API", as this API were
|
||||
added originally_enabled to provide support for DVB-S2), because the
|
||||
old API has a very limited support to new standards and new hardware.
|
||||
This section describes the new and recommended way to set the frontend,
|
||||
with suppports all digital TV delivery systems.
|
||||
1. On Linux DVB API version 3, setting a frontend was done via
|
||||
struct :c:type:`dvb_frontend_parameters`.
|
||||
|
||||
Example: with the properties based approach, in order to set the tuner
|
||||
to a DVB-C channel at 651 kHz, modulated with 256-QAM, FEC 3/4 and
|
||||
symbol rate of 5.217 Mbauds, those properties should be sent to
|
||||
2. Don't use DVB API version 3 calls on hardware with supports
|
||||
newer standards. Such API provides no suport or a very limited
|
||||
support to new standards and/or new hardware.
|
||||
|
||||
3. Nowadays, most frontends support multiple delivery systems.
|
||||
Only with DVB API version 5 calls it is possible to switch between
|
||||
the multiple delivery systems supported by a frontend.
|
||||
|
||||
4. DVB API version 5 is also called *S2API*, as the first
|
||||
new standard added to it was DVB-S2.
|
||||
|
||||
**Example**: in order to set the hardware to tune into a DVB-C channel
|
||||
at 651 kHz, modulated with 256-QAM, FEC 3/4 and symbol rate of 5.217
|
||||
Mbauds, those properties should be sent to
|
||||
