This patchset adds a GPIO driver for Tegra2 SoC, and enables it for all boards
Changes in V2: - use 'gpio_pin' enum in gpio.h (Simon Glass review request) - change 'GPIO_PORT8' to 'GPIO_FULLPORT' (Simon Glass request) - change 'offset' to 'pin' globally - enable GPIO for all boards (tegra2-common.h) Changes in V3: - use common cmd_gpio; remove redundant cmd processing code - add gpio_request, gpio_free and gpio_toggle - alias 'gpio_status' to 'gpio_info' for use in cmd_gpio Changes in V4: - update code as per Mike Frysinger's review comments - rewrite gpio_info, aka gpio_status
