From 0433cd28f3a421e0be708c856c7d0c66d3f60bd7 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 9 Dec 2011 08:01:01 -0200 Subject: [PATCH] [media] xc5000: Add support for 7MHz bandwidth for DVB-C/DVB-T While xc5000 supports 7MHz bandwidth, the driver were lacking the code implementing this feature, causing tuning issues with VHF chanels used in Countries like Italy.
