Detailed Description

struct samsung_gpio_cfg GPIO configuration : Configuration setting when used for external interrupt source : Read the current pull configuration for the GPIO : Set the current pull configuraiton for the GPIO : Set the current configuration for the GPIO : Read the current configuration for the GPIO

Each chip can have more than one type of GPIO bank available and some have different capabilites even when they have the same control register layouts. Provide an point to vector control routine and provide any per-bank configuration information that other systems such as the external interrupt code will need.
