nmk_config_pin - configure a pin's mux attributes : pin confguration : Non-zero to apply the sleep mode configuration Configures a pin's mode (alternate function or GPIO), its pull up status, and its sleep mode based on the specified configuration. The is usually one of the SoC specific macros defined in mach/<soc>-pins.h. These are constructed using, and can be further enhanced with, the macros in plat/pincfg.h.
If a pin's mode is set to GPIO, it is configured as an input to avoid side-effects. The gpio can be manipulated later using standard GPIO API calls.

nmk_config_pins - configure several pins at once : array of pin configurations : number of elments in the array
Configures several pins using nmk_config_pin(). Refer to that function for further information.
