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
