Subject: [PATCH v2 0/7] ARM: OMAP1: ams-delta: replace custom I/O with GPIO

The Amstrad Delta board has two extra output ports used for driving
input lines of different on-board devices. Those ports are now
controlled with custom functions, provided by the board arch code and
used by several device drivers.

The idea behind the series is to replace those custom I/O functions
with gpiolib API. This way, existing drivers can be made less platform
dependent, and some of them perhaps even superseded with generic GPIO
based drivers after the board platform device descriptions are
converted. Moreover, should a new driver for the on-board Smart Card
controller ever be created, it could be designed as a generic GPIO
based driver, not a custom one.

Changes against initial version:
* the initial patch, which tried to move the gpio-generic driver
  initialization up to the postcore_initcall level, replaced with an
  alternative solution, moving the on-board devices initialization down
  to late_initcall; thanks to Tony Lindgren who suggested this solution,
* dropped patches introducing changes to the modem and ASoC device
  handling; those will be addressed in a separate patch series,
* final cleanups also dropped until those remaining devices are updated,
* the serio driver now takes care of one more GPIO pin which, even if
  not used, belongs to the device interface and affects its functioning,
* misc code and changelog cosmetic cleanups,
* rebased on top of 3.2-rc6.

Thanks to those who reviewed the initial submission and responded with
their comments or Acks.
