Enumeration Type Documentation

enum eint_type

enum eint_type - possible external interrupt types. : bank does not support external interrupts : bank supportes external gpio interrupts : bank supportes external wakeup interrupts

Samsung GPIO controller groups all the available pins into banks. The pins in a pin bank can support external gpio interrupts or external wakeup interrupts or no interrupts at all. From a software perspective, the only difference between external gpio and external wakeup interrupts is that the wakeup interrupts can additionally wakeup the system if it is in suspended state.

Enumerator:

EINT_TYPE_NONE
EINT_TYPE_GPIO
EINT_TYPE_WKUP
