2018-05-16	gpio: eic: Add edge trigger emulation for EIC	Baolin Wang	1	-0/+73
	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	1	-0/+606
	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.
