| 2018-05-16 | gpio: eic: Add edge trigger emulation for EIC | Baolin Wang | |
| The Spreadtrum debounce EIC and latch EIC can not support edge trigger, but most GPIO users (like gpio-key driver) only use the edge trigger, thus the EIC driver need add some support to emulate the edge trigger to satisfy this requirement.

| 2018-03-27 | gpio: Add Spreadtrum EIC driver support | Baolin Wang | |
| The Spreadtrum digital-chip EIC controller has 4 sub-modules: debounce EIC, latch EIC, async EIC and sync EIC, and each sub-module can has multiple banks and each bank contains 8 EICs. Each EIC can only be used as input mode, and has the capability to trigger interrupts when detecting input signals.
