From a18255bef2a62632ed442fdb90b091193cbabca5 Mon Sep 17 00:00:00 2001 From: Hartmut Birr Date: Thu, 9 Aug 2007 00:01:51 -0300 Subject: V4L/DVB (5985): Fix the min/max frequencies of some DVB-C frontends The min frequencies of the DVB-C frontends are wrong. In Europe, the center frequency of the lowest channel is 50.5MHz and not 51MHz. All known cards with the stv0297/tda0002x/ves1820 frontend are able to tune to this frequency. I've changed the range to the lowest channel - 1/2 bandwidth and the highest channel + 1/2 bandwidth. For the design of the dvb driver, the frequency ranges must be part of the tuner and not of the frontend itself. The same frontend may be used for different tuners. The attached patch does only fix the ranges and not the design.
