I initially got involved into this by finding out about Daniel's
Gentoo overlay carrying ddbridge-sources, which installs the gentoo
kernel sources with these exact patches ontop. The first version I
tried was with kernel 4.9 which had an older revision of the patchset,
and am now up at version 4.12.3, having the patches posted here ontop
of a stable kernel version.

Air-borne TV in Munich, Germany is DVB-T2 _only_ since March 29, 2017.

+1:     The pach set is working to my perfect satisfaction:

Displaying channels works flawlessly with VLC and Kaffeine.
For recording I exploit Kaffeine's comfortable graphical user interface.

        media-video/kaffeine-9999:5         (latest git)
        media-video/vlc-2.2.6-r1:0/5-8

I am grateful for Daniels support, always quick and friendly,
to help me get up and running in the beginning,
as well as his cooperation and very fast reaction lately:

Integrating into cxd2841er in

. . . sys-kernel/ddbridge-sources-4.12.0   ( CONFIG_DVB_CXD2841ER )

resulted in failure of scanning for channels within Kaffeine.
Daniel's patch [1] fixed the underlying deeper problem:
. . . changing from DVB-T to DVB-T2 without stopping the frontend,
. . . the demod operation mode isn't re-setup
(Mauro <mchehab> was on CC).

It was immediately integrated (amongst other improvements) by Daniel into

. . . sys-kernel/ddbridge-sources-4.12.{1,2,3}

delivering the services mentioned above as solid as expected.

Many "Thanks!" to Daniel - and to the reviewers.

+1:     for integrating this cleaned-up structure into mainline

This rescues users of DD HW from being enslaved by DD's
   "one big undocumented blob for everything"
   "only our HW counts" "exclude all other media hw"
attitude.

Personally, I want a clean HW driver *only*,
and disgust being forced into installing an inscrutable "Octopus" network
compulsorily just for being able to use a tiny bit of HW locally.

Regards,

Manfred
