Subject: [PATCH AUTOSEL 4.19 425/671] rtc: pcf8563: Fix interrupt trigger method
Date: Thu, 16 Jan 2020 12:01:03 -0500 [thread overview]
Message-ID: <20200116170509.12787-162-sashal@kernel.org> (raw)
In-Reply-To: <20200116170509.12787-1-sashal@kernel.org>
From: Chen-Yu Tsai <wens@csie.org>
[ Upstream commit 65f662cbf829834fa4d94190eb7691e5a9cb92d8 ]
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.
Fixes: ede3e9d47cca ("drivers/rtc/rtc-pcf8563.c: add alarm support")
