From 65f662cbf829834fa4d94190eb7691e5a9cb92d8 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 4 Jun 2019 12:23:35 +0800 Subject: rtc: pcf8563: Fix interrupt trigger method The PCF8563 datasheet says the interrupt line is active low and stays active until the events are cleared, i.e. a level trigger interrupt. Fix the flags used to request the interrupt.
