+ tristate "Pluto2 cards"
+ depends on DVB_CORE && PCI && I2C
+ select I2C_ALGOBIT
+ select DVB_TDA1004X
+ help
+ Support for PCI cards based on the Pluto2 FPGA like the Satelco
+ Easywatch Mobile Terrestrial DVB-T Receiver.
+
+ Since these cards have no MPEG decoder onboard, they transmit
+ only compressed MPEG data over the PCI bus, so you need
+ an external software decoder to watch TV on your computer.
+
+ Say Y or M if you own such a device and want to use it.
