+ This adds support for DVB front-end cards connected
+ to TS inputs of STiH407/410 SoC.
+
+ The driver currently supports C8SECTPFE's TS input block,
+ memdma engine, and HW PID filtering.
+
+ Supported DVB front-end cards are:
+ - STMicroelectronics DVB-T B2100A (STV0367 + TDA18212)
+ - STMicroelectronics DVB-S/S2 STV0903 + STV6110 + LNBP24 board
+
+ To compile this driver as a module, choose M here: the
+ module will be called c8sectpfe.
