[PATCH 1/3] rtc: pcf8563: Fix interrupt trigger method

From: Chen-Yu Tsai
Date: Tue Jun 04 2019 - 00:27:45 EST

From: Chen-Yu Tsai <wens@xxxxxxxx>

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")
Signed-off-by: Chen-Yu Tsai <wens@xxxxxxxx>

Not sure if this would cause issues for other platforms. Ideally we'd
take the flags from the device tree, but it seems not all platforms
support this.
