Subject: [media] xc5000: Add support for DMB-TH and ISDB-T
X-Git-Tag: Ubuntu-snapdragon-4.4.0-1029.32~12737^2^2~86
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=5cf73ce15f704876378733794864336fbec6c97e;p=mirror_ubuntu-zesty-kernel.git

[media] xc5000: Add support for DMB-TH and ISDB-T

xc5000 is just a tuner, not a decoder, so both DMB-TH and ISDB-T should
work properly there: it is just a matter of teaching the driver what
saw filter should be used and how to calculate the center frequency.
