From 07aa5cf3af823ab2e7ce90cf147845363a35675c Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Mon, 25 Jan 2021 19:47:30 +0100 Subject: [PATCH] ARM: dts: imx6: RDU2: only trigger IRQ on falling edge ucs1002 ALERT pin The ALERT signaling happens on the falling edge of the signal, as rising edge doesn't really have any notion, as it may happen much later (due to shared IRQ line) or too early if the chip resolves the fault itself. So only trigger the IRQ on the edge we are actually interested in.
