> Multiprotocol transceivers such as the LTC2873 provide both an RS232
> and an RS485 interface on the same bus pins and choose between them
> with an interface select input: on the LTC2873 a logic low on the
> 485/232 pin enables RS232 mode and a high enables RS485 mode.
> 
> Add an optional rs485-select-gpios property for that input, next to
> the existing rs485-term-gpios and rs485-rx-during-tx-gpios. The active
> state selects the RS485 interface, the inactive state selects the
> transceiver's alternative interface, RS232 on the LTC2873.
