102 * 1: pin high set to VOLTAGE_13, pin low to set VOLTAGE_18.
103 * 0: pin high set to VOLTAGE_18, pin low to set VOLTAGE_13.
108 * LNB enable pin polarity
110 * 1: pin high to enable, pin low to disable.
111 * 0: pin high to disable, pin low to enable.
117 * Driver implements own I2C-adapter for tuner I2C access. That's since chip
118 * has I2C-gate control which closes gate automatically after I2C transfer.
119 * Using own I2C adapter we can workaround that.
