What's the purpose of being able to define both states? AFAIK
omap_serial.c is working as follows:
if (of_property_read_bool(np, "rs485-rts-active-high"))
rs485conf->flags |= SER_RS485_RTS_ON_SEND;
else
rs485conf->flags |= SER_RS485_RTS_AFTER_SEND;
If RTS should be on before send, then it automatically selects RTS off
for after send scenario. Are there systems, that would really set
levels for both cases to the same value? Is this intended for RS422
case, where transmitter can be always on?
