3 The EIC is the abbreviation of external interrupt controller, which can
4 be used only in input mode. The Spreadtrum platform has 2 EIC controllers,
5 one is in digital chip, and another one is in PMIC. The digital chip EIC
6 controller contains 4 sub-modules: EIC-debounce, EIC-latch, EIC-async and
7 EIC-sync. But the PMIC EIC controller contains only one EIC-debounce sub-
10 The EIC-debounce sub-module provides up to 8 source input signal
12 stable status (millisecond resolution) and a single-trigger mechanism
13 is introduced into this sub-module to enhance the input event detection
14 reliability. In addition, this sub-module's clock can be shut off
