[PATCH 6/9] serial: imx: default to half duplex rs485

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




From: Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>

The i.MX driver defaulted to full duplex rs485 which is rather
unusual and doesn't match the default implemented in other drivers.

So change the default to half duplex.
