10d67371fc [media] DVB: remove "stats" property bits from ATSC-MH API property additions
Mauro is proposing a new API to handle statistics. This functionality will
be returned after the statistics API is ready. Just remove them for now.

8de8594a79 [media] dvb-core: be sure that drivers won't use DVBv3 internally
Now that all frontends are implementing DVBv5, don't export the
DVBv3 specific stuff to the drivers. Only the core should be
aware of that, as it will keep providing DVBv3 backward compatibility.

fd66c45dd5 [media] Remove Annex A/C selection via roll-off factor
Instead of using a roll-off factor, change DRX-K & friends to select
the bandwidth filter and the Nyquist half roll-off via delivery system.

This provides a cleaner support for Annex A/C switch.

ba2780c796 [media] DVB: Query DVB frontend delivery capabilities
Currently, for any multi-standard frontend it is assumed that it just
 has a single standard capability. This is fine in some cases, but
 makes things hard when there are incompatible standards in conjuction.
 Eg: DVB-S can be seen as a subset of DVB-S2, but the same doesn't hold
 the same for DSS. This is not specific to any driver as it is, but a
 generic issue. This was handled correctly in the multiproto tree,
 while such functionality is missing from the v5 API update.

 http://www.linuxtv.org/pipermail/vdr/2008-November/018417.html

 Later on a FE_CAN_2G_MODULATION was added as a hack to workaround this
 issue in the v5 API, but that hack is incapable of addressing the
 issue, as it can be used to simply distinguish between DVB-S and
 DVB-S2 alone, or another X vs X2 modulation. If there are more systems,
 then you have a potential issue.

 An application needs to query the device capabilities before requesting
 any operation from the device.

39ce61a846 [media] dvb: Allow select between DVB-C Annex A and Annex C
DVB-C, as defined by ITU-T J.83 has 3 annexes. The differences between
Annex A and Annex C is that Annex C uses a subset of the modulation
types, and uses a different rolloff factor. A different rolloff means
that the bandwidth required is slicely different, and may affect the
saw filter configuration at the tuners. Also, some demods have different
configurations, depending on using Annex A or Annex C.

So, allow userspace to specify it, by changing the rolloff factor.

f6a20eb1a2 V4L/DVB: Add FE_CAN_TURBO_FEC
Some (North American) providers use a non-standard mode called
"8psk turbo fec". Since there is no flag in the driver that
would allow an application to determine whether a particular
device can handle "turbo fec", the attached patch introduces
FE_CAN_TURBO_FEC.

Since there is no flag in the SI data that would indicate
that a transponder uses "turbo fec", VDR will assume that
all 8psk transponders on DVB-S use "turbo fec".

98293ef3e5 V4L/DVB (12997): Add the DTV_ISDB_TS_ID property for ISDB_S
In ISDB-S, time-devision duplex is used to multiplexing several waves
in the same frequency. Each wave is identified by its own transport
stream ID, or TS ID. We need to provide some way to specify this ID
from user applications to handle ISDB-S frontends.

This code has been tested with the Earthsoft PT1 driver.

b6e760f309 V4L/DVB (12892): DVB-API: add support for ISDB-T and ISDB-Tsb (version 5.1)
This patch increments the DVB-API to version 5.1 in order to reflect the addition of ISDB-T and ISDB-Tsb on Linux' DVB-API.

Changes in detail:
- added a small document to describe how to use the API to tune to an ISDB-T or ISDB-Tsb channel
- added necessary fields to dtv_frontend_cache
- added a smarter clear-cache function which resets all fields of the dtv_frontend_cache
- added a TRANSMISSION_MODE_4K to fe_transmit_mode_t

cb889a2f35 V4L/DVB (10164): Add missing S2 caps flag to S2API
The attached patch adds a capability flag that allows an application
to determine whether a particular device can handle "second generation
modulation" transponders. This is necessary in order for applications
to be able to decide which device to use for a given channel in
a multi device environment, where DVB-S and DVB-S2 devices are mixed.

It is assumed that a device capable of handling "second generation
modulation" can implicitly handle "first generation modulation".
The flag is not named anything with DVBS2 in order to allow its
use with future DVBT2 devices as well (should they ever come).
