To prevent breakage and unexpected dependencies this support only is only built if CONFIG_IIO is enabled, and is only weakly referenced by 'imply IIO' within the respective Kconfig. Additionally the iio device only gets registered if at least one channel is enabled in the power-on configuration read from SRAM.
