Hello,

this is the reworked series to address the handshaking problems I saw.

Among others it made my i.MX25 stuck when the other side toggles DCD.
The first 4 patches are fixes that I'd like to see in 4.6-rcX, the last two
patches are merge window material.

Best regards
Uwe

  serial: imx: fix polarity of RI
  serial: imx: let irq handler return IRQ_NONE if no event was handled
  serial: imx: make sure unhandled irqs are disabled
  serial: imx: only count 0->1 transitions for RNG
  serial: imx: reorder functions to simplify next patch
  serial: imx: implement DSR irq handling for DTE mode
