SubjectRe: [PATCH 00/15] Improve DVB documentation and reduce its gap

I agree that av7110 is very very old piece of hw (but it is already
in my hall of fame because of its Skystar 1 incarnation as
first implementation of DVB in Linux) and it is sad that we still
don't have at least one driver for any SoC with embedded DVB
devices.

I understand that the main issue is that no any DVB-enabled
SoC vendor is interested in upstreaming theirs code, but I still hope
it will change in near future(*)

Without having full-featured DVB device in vanilla, we surely don't
get some parts of DVB API covered. I can imagine that when
somebody comes with such full-featured device he wants to reinvent
just removed bits.

It's my 5 cents

(*) My favourite is HiSilicon with very nice Hi3798 4K chip
with announced support from Linaro and already available
devboard for reasonable price.

PS: I'm in no any way connected with HiSilicon nor
any other DVB-enabled SoC vendor.
