[U-Boot] [PATCH V4 0/2] GPIO: Tegra2: add GPIO driver for Tegra2

[Tom Warren]

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
