Simon Glassf94a1be2015-02-05 21:41:35 -0700[diff] [blame]11 Enable driver model for GPIO access. The standard GPIO
12 interface (gpio_get_value(), etc.) is then implemented by
13 the GPIO uclass. Drivers provide methods to query the
14 particular GPIOs that they provide. The uclass interface
15 is defined in include/asm-generic/gpio.h.
