[PATCH 5/9] serial: omap-serial: Use common rs485 device tree parsing function

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

 



From: Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>

We just got a common helper for parsing the rs485 specific
device tree properties. Use it and drop the open coded parser.
Note that the common helper is more strict and only evaluates the
optional properties if the required rs485-rts-delay is present.
