There are a number of other ioctls that aren't used anywhere
inside the Kernel tree.

Get rid of them.

media: dvb: get rid of VIDEO_SET_SPU_PALETTE

2018-07-27T10:41:35+00:00

No upstream drivers use it. It doesn't make any sense to have
a compat32 code for something that nobody uses upstream.

media: update/fix my e-mail on some places

2018-05-10T11:27:15+00:00

There are two places pointing to an unexisting "m.chehab@kernel.org"
email. I never had such email, so, I'm unsure how it ends there.
Anyway, it is plain wrong.

While here, use my canonical e-mail on a bunch of places that
are pointing to another e-mail. The idea is that, from now on,
all places will be pointing to the same SMTP server.

media: dvb: add continuity error indicators for memory mapped buffers

2018-02-23T10:28:41+00:00

While userspace can detect discontinuity errors, it is useful to
also let Kernelspace reporting discontinuity, as it can help to
identify if the data loss happened either at Kernel or userspace side.

Update documentation accordingly.

media: dvb-core: get rid of mmap reserved field

2017-12-28T16:17:31+00:00

The "reserved" field was a way, used at V4L2 API, to add new
data to existing structs without breaking userspace. However,
there are now clever ways of doing that, without needing to add
an uneeded overhead. So, get rid of them.

media: dvb uAPI docs: document mmap-related ioctls

2017-12-28T16:17:30+00:00

5 new ioctls were added to the DVB demux API, in order to
handle memory maped I/O. Add documentation for them.

2017-12-28T16:17:30+00:00

With the new dmx mmap interface, those two syscalls are now
handled by the subsystem. Document them.

This patch is based on the V4L2 text for those ioctls.

media: dvb_frontend: add physical layer scrambling support

2017-12-19T12:08:12+00:00

This commit adds a new property DTV_SCRAMBLING_SEQUENCE_INDEX.

This 18 bit field, when present, carries the index of the DVB-S2 physical
layer scrambling sequence as defined in clause 5.5.4 of EN 302 307.
There is no explicit signalling method to convey scrambling sequence index
to the receiver. If S2 satellite delivery system descriptor is available
it can be used to read the scrambling sequence index (EN 300 468 table 41).

By default, gold scrambling sequence index 0 is used. The valid scrambling
sequence index range is from 0 to 262142.

Increase the DVB API version in order userspace to be aware of the changes.
