    description: |

       Defines the configuration and output drive for the General Purpose

       Input and Output pin (GPIO1). Its value is a pair, the first value is for

       the configuration type and the second value is for the output drive

       type. The array is defined as <GPIO1_CFG GPIO1_DRV>



       configuration for the GPIO pin can be one of the following:

       0 - disabled

       1 - GPIO1 is configured as a general-purpose output (GPO)

       2 - (default) GPIO1 is configured as a device interrupt output (IRQ)

       3 - GPIO1 is configured as a secondary ASI output (SDOUT2)

       4 - GPIO1 is configured as a PDM clock output (PDMCLK)

       8 - GPIO1 is configured as an input to control when MICBIAS turns on or

           off (MICBIAS_EN)

       9 - GPIO1 is configured as a general-purpose input (GPI)

       10 - GPIO1 is configured as a master clock input (MCLK)

       11 - GPIO1 is configured as an ASI input for daisy-chain (SDIN)

       12 - GPIO1 is configured as a PDM data input for channel 1 and channel 2

            (PDMDIN1)

       13 - GPIO1 is configured as a PDM data input for channel 3 and channel 4

            (PDMDIN2)

       14 - GPIO1 is configured as a PDM data input for channel 5 and channel 6

            (PDMDIN3)

       15 - GPIO1 is configured as a PDM data input for channel 7 and channel 8

            (PDMDIN4)



       output drive type for the GPIO pin can be one of the following:

       0 - Hi-Z output

       1 - Drive active low and active high

       2 - (default) Drive active low and weak high

       3 - Drive active low and Hi-Z

       4 - Drive weak low and active high

       5 - Drive Hi-Z and active high
