help
- If you want to use driver model for GPIO drivers, say Y.
- To use legacy GPIO drivers, say N.
+ 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.
