[PATCH RFC 0/7] serial: imx: fix RTS and RTS/CTS handling

Dear Sascha,

I think these patches deliver simpler end result and are more complete
than what you just posted. In particular, the

  serial: imx: set_mctrl(): correctly restore autoRTS state

addresses exactly the issue your patch is about, but in a slightly
simpler manner.

The patches are not tested yet, so I've put RFC in the header. Just my
2 cents. I can obviously re-roll them on top of your work later, if
required.

Sergey Organov (7):
  serial: imx: fix locking in set_termios()
  serial: imx: set_termios(): factor-out 'ucr2' initial value
  serial: imx: set_termios(): clarify RTS/CTS bits calculation
  serial: imx: set_termios(): do not enable autoRTS if RTS is unset
  serial: imx: set_termios(): preserve RTS state
  serial: imx: set_mctrl(): correctly restore autoRTS state
  serial: imx: get rid of imx_uart_rts_auto()
