V4L/DVB (13493): TeVii S470 and TBS 6920 fixes
The new hardware design applied for this cards. Silicon Labs C8051F300 microcontroller is used for LNB power control. It connected to cx23885 GPIO pins: GPIO0 - P0.3 data GPIO1 - P0.2 reset GPIO2 - P0.1 clk GPIO3 - P0.0 busy Tevii S470 based on Montage Technology M88TS2020 digital satellite tuner and M88DS3000 advanced DVB-S/S2 demodulator.
