Merge branch 'gpio/next' of git://git.secretlab.ca/git/linux-2.6
* 'gpio/next' of git://git.secretlab.ca/git/linux-2.6:
gpio/via: rename VIA local config struct
basic_mmio_gpio: split into a gpio library and platform device
gpio: remove some legacy comments in build files
gpio: add trace events for setting direction and value
gpio/pca953x: Use handle_simple_irq instead of handle_edge_irq
gpiolib: export gpiochip_find
gpio: remove redundant Kconfig depends on GPIOLIB
basic_mmio_gpio: convert to non-__raw* accessors
basic_mmio_gpio: support direction registers
basic_mmio_gpio: support different input/output registers
basic_mmio_gpio: detect output method at probe time
basic_mmio_gpio: request register regions
basic_mmio_gpio: allow overriding number of gpio
basic_mmio_gpio: convert to platform_{get,set}_drvdata()
basic_mmio_gpio: remove runtime width/endianness evaluation
