Typedefs
typedef void(*	uart_mux_attach_cb_t) (const struct device *mux, int dlci_address, bool connected, void *user_data)
	Define the user callback function which is called when the UART mux is attached properly.
typedef void(*	uart_mux_cb_t) (const struct device *uart, const struct device *dev, int dlci_address, void *user_data)
	Callback used while iterating over UART muxes.

Functions
static int	uart_mux_attach (const struct device *mux, const struct device *uart, int dlci_address, uart_mux_attach_cb_t cb, void *user_data)
	Attach physical/real UART to UART muxing device.
const struct device *	uart_mux_find (int dlci_address)
	Get UART related to a specific DLCI channel.
const struct device *	uart_mux_alloc (void)
	Allocate muxing UART device.
void	uart_mux_foreach (uart_mux_cb_t cb, void *user_data)
	Go through all the UART muxes and call callback for each of them.
void	uart_mux_disable (const struct device *dev)
	Disable the mux.
void	uart_mux_enable (const struct device *dev)
	Enable the mux.
