[media] stb0899: allow minimum symbol rate of 2000000
Looks like product datasheets for tuners containing STB0899 are suggesting specification for min. symbol rate of 2MS/s. Some specs found here, all suggesting 2MS/s for min. symbol rate: Comtech DVBS2-6899 http://comtech.sg1002.myweb.hinet.net/pdf/dvbs2-6899.pdf TechniSat SkyStar HD2 http://www.scaistar.com/skystar2/skystarhd2.htm Azurewave AD-SP400 http://www.pulsat.com/products/AzureWave-AD%252dSP400-High-Definition-PC-Card.html New patch: This makes minimum symbol rate driver capabilities on par with some accessible datasheet specifications*, and allows tuning on linux to transponders that have symbol rate between 2000000-5000000, too. Patch was tested successfully on Eutelsat 16A transponders that became reachable with it (2000000 < symbol rate < 5000000): * DVB/S 12507050 V 2532000 3/4 * DVB/S2 12574000 V 4355000 3/4 8PSK * DVB/S 12593000 V 2500000 2/3 * DVB/S 12596940 V 2848000 2/3 * DVB/S 12600750 V 2500000 1/2 * DVB/S 12675590 H 4248000 3/4 (*) Datasheet: http://comtech.sg1002.myweb.hinet.net/pdf/dvbs2-6899.pdf Maximum Symbol Rate QPSK/LDPC/PCH: 20-30Mbps 8PSK/LDPC/BCH: 10-30Mbps DVB: 2-45Mbps ^--------- min. symbol rate Signed-off-by: Zoran Turalija <zoran.turalija@gmail.com> Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
