Vadim Catana 1c956a3ac0 DVB (2451): Add support for KWorld DVB-S 100, based on the same chips as Hauppauge
- Add support for KWorld DVB-S 100, based on the same chips as Hauppauge
Nova-S Plus (CX23883/CX24123/CX24109), without the Intersil ISL6421,
which is used for LNB control.
- LNB voltage and tone are controled by LNBDC and LNBTone bits from
register 0x29 of the CX24123 demodulator.
- The MO_GP0_IO register from CX23883 is used to turn LNB power on and off.
