According to the documentation gpio_free should only be called from task
context only. To make this more explicit add a might sleep to all
implementations.
This patch changes the gpio_free implementations for the arm architecture.
DaVinci is skipped on purpose to simplify the merge process for patches
switching it over to use gpiolib as per request by David Brownell.

This patch against 2.6.27-rc3 does the following changes to FSG-3 setup code:
1) Enable RTC on FSG-3 (proper name is needed). This change is needed due to a recent change in i2c.
2) i variable is only used when compiling for big endian.
So move its declaration to ARMEB ifdef to silence the warning when compiling for LE.

Based on earlier work by Jon Smirl and Jochen Friedrich.
Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.

The Freecom-FSG3 is a small network-attached-storage device with the
following feature set:
* Intel IXP422
* 4MB Flash (ixp4xx flash driver)
* 64MB RAM
* 4 USB 2.0 host ports (ehci and ohci drivers)
* 1 WAN (eth1) and 3 LAN (eth0) ethernet ports
* Supported by the open source ixp4xx ethernet driver
* Via VT6421 disk controller (libata and sata-via drivers)
* Internal hard disk (PATA supported, SATA not yet supported)
* External SATA port (not yet supported)
* ISL1208 RTC chip
* Winbond 83782 temp sensor and fan controller
* MiniPCI slot
The ixp4xx_defconfig is also updated to support this device (the
leds-fsg driver is to be submitted separately via the leds tree after
this initial support is merged, as it depends on header gpio defines).
