From 102bbe34b31c9159e714432afd64458f6f3876d7 Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Wed, 10 Apr 2019 15:47:54 +0800 Subject: gpio: eic: sprd: Fix incorrect irq type setting for the sync EIC When setting sync EIC as IRQ_TYPE_EDGE_BOTH type, we missed to set the SPRD_EIC_SYNC_INTMODE register to 0, which means detecting edge signals. Thus this patch fixes the issue.
