[patch 2.6.28-rc5 0/5] twl4030 irq assignments

[David Brownell <david-b@pacbell.net>]

The following patches remove some needless dependencies from
TWL4030 support, supporting non-OMAP builds and in some cases,
non-SDP (etc) builds.

 - keypad driver ... use platform_get_irq(), no board dependencies
 - BCI driver ... likewise
 - MADC driver ... use platform_get_irq()
 - power button ... still pretty hacky, there's no device here
 - removes the now-dead symbols, and OMAP-dependency

Build-tested.

With this, I think the keypad driver becomes ready to go upstream,
after related twl4030-core updates.  At least, it's ready for review.
(Including:  Why pass the keypad module id to kpread/kpwrite, it's
the only one ever used?  Why does Kconfig mention GPIOs, since they
aren't used?)

The point of these patches is that last one, which lets non-OMAP
folk do test builds and easily make updates when APIs change.
Yeah, it's a strange notion, but not everyone does OMAP builds.  ;)
