[PATCH 0/5] tty/serial: Add helpers to use GPIOs to control modem lines and implement atmel_serial.c

[Richard Genoud]

This patch series is a leftover of http://www.spinics.net/lists/arm-kernel/msg314242.html
that missed 3.15 because it caused merge conflicts.

The 1st patch may be applied as a fix for 3.15-rc, since it correct a
device tree binding documentation example.

Greg, for you to decide if it's worth it or not !

It's based on v3.15-rc2.

  tty/serial: Add GPIOLIB helpers for controlling modem lines
