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
