1c2c30acc5 mfd: have TMIO drivers and subdevices depend on ARM
The TMIO chips are only found (and thus tested) on ARM machines.
Moreover, we don't want the TMIO cells to be built if one of the TMIO
driver is not selected (which indirectly make the TMIO cells drivers
depend on ARM as well).

cbdfb42639 mfd: driver for the TC6387XB TMIO controller.
This patch adds support for the TC6387XB. Unlike other TMIO devices this one
has only one subdevice and no interrupt mux, however using the MFD framework
allows it to share the TMIO MMC driver.

7444a72eff gpiolib: allow user-selection
This patch adds functionality to the gpio-lib subsystem to make it
possible to enable the gpio-lib code even if the architecture code didn't
request to get it built in.

The archtitecture code does still need to implement the gpiolib accessor
functions in its asm/gpio.h file.  This patch adds the implementations for
x86 and PPC.

With these changes it is possible to run generic GPIO expansion cards on
every architecture that implements the trivial wrapper functions.  Support
for more architectures can easily be added.

fa9ff4b185 ASIC3 driver
This is a patch for the Compaq ASIC3 multi function chip, found in many
PDAs (iPAQs, HTCs...).

It is a simplified version of Paul Sokolovsky's first proposal [1].  With
this code, it is basically a GPIO and IRQ expander.  My plan is to add more
features once this patch gets reviewed and accepted.

01dd2fbf0d typo fixes
Most of these fixes were already submitted for old kernel versions, and were
approved, but for some reason they never made it into the releases.

Because this is a consolidation of a couple old missed patches, it touches both
Kconfigs and documentation texts.
