From f7f3b484d5505b9a8f09d9db6a2ec172d7f49e0f Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 2 Oct 2016 18:44:35 +0200 Subject: [PATCH] ARM: dts: imx6sx: Fix LCDIF interrupt type The LCDIF interrupt should be triggered by the rising edge of the IRQ line because we only want the interrupt to trigger once per each frame. It seems the LCDIF IRQ line cannot be explicitly de-asserted by software, so the previous behavior before this patch, where the interrupt was triggered by level-high status of the IRQ line, caused the interrupt to fire again immediatelly after it was handled, which caused the system to lock up due to the high rate of interrupts.
