From: Sascha Hauer <s.hauer@pengutronix.de> We just got a common helper for parsing the rs485 specific device tree properties. Use it and drop the open coded parser. As a side effect this adds support for parsing rs485-rts-delay and rs485-rx-during-tx. As the driver doesn't support this though, probing fails if these are defined.
