+        tristate "Pluto2 cards"
+        depends on DVB_CORE && PCI && I2C

+        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.
