[patch 2.6.27-omap-git+ 0/5] twl4030 GPIO updates

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

Following this are several patches making the twl4030 GPIO code
fit better into the GPIO framework, updating its only current
user (hsmmc glue) and adding one more (Beagle).

 - gpio_request()/gpio_free() hook, now in MM for 2.6.28-rc merge
 - use that mechanism for twl4040 GPIOs
 - remove most twl-specific calls from mach-omap2/hsmmc.c glue
 - support LEDA and LEDB as output-only GPIOs
 - support those two LED signals on Beagle (one is a real LED!)

This goes on top of the preceding patches to update IRQ handling
for the twl core.

Capsule summary:  the only remaining twl40-specific GPIO calls
are to enable hardware debouncing, with potential upstream generic
support soon; and disabled linkages of the MMC power supplies to
those card detect lines (best suited IMO to platform_data, once
it's tested).

Which makes twl4030-gpio nearly ready to go upstream.
