> E810-T adapters have two external bidirectional SMA connectors and two internal unidirectional U.FL connectors. Multiplexing between U.FL and SMA and SMA direction is controlled using the PCA9575 expander.
>
> Add support for the PCA9575 detection and control of the respective pins of the SMA/U.FL multiplexer using the GPIO AQ API.
