[PATCH 2/9] Documentation: serial-rs485: document SER_RS485_DELAY_IN_USEC flag

[-- 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).
