Hi Antti,
Mauro asked me to look into LNA as well, in particular how this could be done
on the analog side as well.
While reading through this patch I noticed that the new property was added to
dtv_property_process_set, but not to dtv_property_process_get. Can you look
into that and add 'get' support for this property?
Thanks!
Hans
