linux-toradex.git/drivers/gpio/gpio-pmic-eic-sprd.c, branch v5.1-rc4 Linux kernel for Apalis and Colibri modules gpio: sprd: Change to use SoC compatible string 2019-02-21T12:18:49+00:00 Baolin Wang baolin.wang@linaro.org 2019-02-19T02:29:58+00:00 567cbf07caf2083a413f7ddf07970b04cc3b38da Change to use SoC compatible string instead of wildcard string. The Spreadtrum SC9860 platform device trees and drivers' development are still in progress, and now we will always recompile and ship device trees at the same time as we will compile and ship the kernel, so we do not need care about the backwards compatibility.

are still in progress, and now we will always recompile and ship
device trees at the same time as we will compile and ship the kernel,

gpio: sprd: Remove unused irq trigger setting 2019-01-21T12:47:12+00:00 Baolin Wang baolin.wang@linaro.org 2019-01-21T05:05:39+00:00 a3f1caeefed0731e64bef39859482e6c9de8f027 The Spreadtrum PMIC interrupt controller has no registers to set irq trigger type, since it is always high level trigger. That means the PMIC EIC controller as a child device of PMIC INTC does not need to set the trigger type, so remove it.

gpio: pmic_eic: Add edge trigger emulation for PMIC EIC 2018-05-16T12:35:24+00:00 Baolin Wang baolin.wang@linaro.org 2018-03-30T07:02:38+00:00 92da8b9deb8795c960e56412e724c3c3c431e06d This patch will toggle the EIC level to emulate the edge trigger to support PMIC EIC egdge trigger function, which is required by gpio-keys driver.

Each EIC can only be used as input mode, as well as supporting the debounce and the capability to trigger interrupts when detecting input signals.
