H A Dgpio-eic-sprd.txt6 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
19 The EIC-latch sub-module is used to latch some special power down signals
20 and generate interrupts, since the EIC-latch does not depend on the APB
23 The EIC-async sub-module uses a 32kHz clock to capture the short signals
26 The EIC-sync is similar with GPIO's input function, which is a synchronized
