63 * The Spreadtrum EIC (external interrupt controller) can be used only in
66 * The Spreadtrum digital-chip EIC controller contains 4 sub-modules:
67 * debounce EIC, latch EIC, async EIC and sync EIC,
69 * The debounce EIC is used to capture the input signals' stable status
70 * (millisecond resolution) and a single-trigger mechanism is introduced
71 * into this sub-module to enhance the input event detection reliability.
