Subject: [media] cxd2820: convert get|set_fontend to use DVBv5 parameters
X-Git-Tag: v3.3-rc1~48^2~229
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f311f68abba633426643bb5e743e4edac4ddf838;p=karo-tx-linux.git

[media] cxd2820: convert get|set_fontend to use DVBv5 parameters

Instead of using dvb_frontend_parameters struct, that were
designed for a subset of the supported standards, use the DVBv5
cache information.

Also, fill the supported delivery systems at dvb_frontend_ops
struct.
