Re: CXD2820 & PCTV nanoStick T2 290e bringup

Hello Steve at all,
Here it is, feel free to test:
http://git.linuxtv.org/anttip/media_tree.git?a=shortlog;h=refs/heads/pctv_290e

Now I *need* help for adding proper DVB-T2 support for the API. I added 
fe_delivery_system_t SYS_DVBT2, but there is no app knowing that yet. 
Since there is also module param to set DVB-T2 frequencies.
For example here is DVB-T2 transmission on channels 570 MHz and 586 MHz. 
You can just type:
echo 570,586 > /sys/module/cxd2820r/parameters/dvbt2_freq
as root, or load driver module following way:
modprobe cxd2820r dvbt2_freq=570,586
for the same.

Also em28xx driver MFE needs review and comments, since I am not sure 
about its correctness.
