The corresponding bits in the output enable register ( BT848_GPIO_OUT_EN) will be set as these pins must be driven by the bt848 chip. The audiomux [] array holds the data values for the different inputs (i.e. which pins must be high/low for tuner/mute/…). This will be written to the data register ( BT848_GPIO_DATA) to switch the audio mux.
