Subject: [PATCH 0/8] serial: 8250: Add 485 emulation to 8250_dw.
Date: Fri,  1 Jun 2018 14:40:13 +0200

Need to handle rs485 with 8250_dw port.

Use existing em485 emulation layer for 8250 taking care to fix some bug
and taking care especially of RTS_AFTER_SEND case.

Giulio Benetti (8):
  serial: 8250_dw: add em485 support
  serial: 8250_dw: allow enable rs485 at boot time
  serial: 8250: Copy em485 from port to real port.
  serial: 8250: Handle case port doesn't have TEMT interrupt using
    em485.
  serial: 8250_dw: treat rpm suspend with -EBUSY if RS485 ON and
    RTS_AFTER_SEND
  serial: 8250: Copy mctrl when register port.
  serial: 8250: Make em485_rts_after_send() set mctrl according to rts
    state.
  serial: core: Mask mctrl with TIOCM_RTS too if rs485 on and
    RTS_AFTER_SEND set.
