2008-12-29V4L/DVB (9462): Allow specifying clock per deviceManu Abraham
Optimizations galore: Blistering barnacles! The KNC1 and friends like 90 Mhz clock much better rather than running at a higher throttle, for almost similar hardware. he exact cause unknown, possibly due to a lower voltage applied for the demod power supply.

2008-12-29V4L/DVB (9443): Bug: Bandwidth calculationManu Abraham
Bug #1: The 5 tap equaliser is set to correct simple perturbations like reflections on the IF cable for DVB-S. In the case of DVB-S2 a more powerful equalizer is used to correct the filter group delay allowing the bandwidth to be reduced by a factor of 1/3 Bug #2: The ZIF tuner takes badwidth to be set in Hz Signed-off-by: Manu Abraham <manu@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9442): Revert back previous change to 90MHzManu Abraham
Note: * At High Symbol Rates we do not have enouph machine cycles to handle the incoming symbols and hence might run into problems at the very end of the specified definition * Most of the equations have been calculated for a master clock of 99 MHz, running at 90MHz, raises lot of issues such as the need to recalculate all of them , which is eventually very painful.

The Bug was found by Arvo Jarve <arvo@softshark.ee> It was a wonder how it worked in the case with this bug, STM verified this that this nibble was in fact insignificant and can be ignored.

2008-12-29V4L/DVB (9433): Limit bandwidth with a 3dB response fallArvo Jarve
In this case, we will be sure that there exists a carrier and the center frequency would be simply f1 - f2. In such a circumstance, the TR loop is simplified to doing a simple check for timing, rather than searching for the same.

2008-12-29V4L/DVB (9430): stb0899: avoid parameter overwritingArvo Jarve
BUG! Setting CRL parameter overwrote the CR Algorithm type, eventually leading to wrong search algorithm to be employed in the DVB-S carrier loop optimization. Symptom: Once the CR optimization stage is passed either way, in a successful or failed manner, the very next carrier search will fail, due to no Carrier Search Algorithm specified.
