+         Enable driver model for GPIO access. The standard GPIO
+         interface (gpio_get_value(), etc.) is then implemented by
+         the GPIO uclass. Drivers provide methods to query the
+         particular GPIOs that they provide. The uclass interface
+         is defined in include/asm-generic/gpio.h.
