moro!
This patch adds i2c_gate_ctrl to QT1010-tuner and ZL10353-demodulator.
Tested successfully against fi-Oulu frequencies with following hw: MSI
Megasky 580 GL861 and Sigmatek DVB-110 AU6610.
changes:
QT1010:
- use i2c_gate_ctrl when accessing to tuner
ZL10353:
- implement i2c_gate_ctrl
- change one reset_attach register to same as main v4l-dvb tree
- leave registers 0x65 and 0x66 to chipset default one... This change
could *break* some other devices using ZL10353 module! Testing needed!
This change is needed to get Megasky GL861 and Sigmatek AU6610 working.
AU6610:
- remove unneeded code due to proper i2c_gate_ctrl
GL861:
- remove unneeded code due to proper i2c_gate_ctrl
