Subject: [PATCH 2/9] Documentation: serial-rs485: document SER_RS485_DELAY_IN_USEC flag
Date: Wed, 20 Feb 2019 16:27:24 +0100	[thread overview]
Message-ID: <20190220152731.4051-2-martin.kepplinger@ginzinger.com> (raw)
In-Reply-To: <20190220152731.4051-1-martin.kepplinger@ginzinger.com>

[-- Attachment #1: Type: text/plain, Size: 916 bytes --]

Document the new RS485 flag, SER_RS485_DELAY_IN_USEC that specifies that the
rts delay values stored in struct serial_rs485 hold values in microseconds
instead of milliseconds (the default).
