93a22f8b95 omap drivers: switch to standard GPIO calls
This updates most of the OMAP drivers which are in mainline to switch to
using the cross-platform GPIO calls instead of the older OMAP-specific
ones.

This is all fairly brainless/obvious stuff.  Probably the most interesting
bit is to observe that the omap-keypad code seems to now have a portable
core that could work with non-OMAP matrix keypads.  (That would improve
with hardware IRQ debouncing enabled, of course...)

various HP9000 machines, which are shared between PA-RISC (suseconds_t is int)
and m68k (suseconds_t is long). As both are 32-bit, it's safe to cast to int.

This adds support for OLPC's touchpad.  It has lots of neat features,

place to deal with the frequent hardware spasms.  Humidity changes,
sweat, tinfoil underwear, plugging in AC, drinks, evil felines.. All
tend to cause the touchpad to freak out.

9ce1ca284a Input: i8042 - make Lenovo 3000 N100 blacklist entry more specific
Apparently, there are more different versions of Lenovo 3000 N100, some
of them working properly with active mux, and some of them requiring it
being switched off.

This patch applies 'nomux' only to the specific product name that is
reported to behave badly unless 'nomux' is specified.

a6821f345f Input: bcm5974 - add BTN_TOUCH event for mousedev benefit
The mousedev driver requires the use of BTN_TOUCH events to process
ABS_X and ABS_Y events properly, which is what is needed for the
bcm5974-based apple computers to have a functional pointer out-of-the-box.

75e21e3f3b Input: bcm5974 - improve finger tracking and counting
The problem of finger tracking, i.e., when to switch focus from one
finger to another on the trackpad, has been improved by utilizing more
information from the bcm5974 chip output. This results in less pointer
hopping when many fingers are on the trackpad. In addition, a finger
counting method based on pressure information from all fingers is
introduced. Together with a pressure hysteresis window, this yields a
more stable counting of the number of fingers on the trackpad.
