From 3050e07453791b8dfecf355a03cee075ec687a55 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Fri, 21 Jan 2022 12:24:57 +0000 Subject: [PATCH] ARM: dts: BCM2711 AON_INTR2 generates IRQ edges THe AON_INTR2 controller manages the HDMI interrupts, combining them into a single interrupt passed to the GIC. bcm2711.dtsi declares the interrupt as being IRQ_TYPE_LEVEL_HIGH, but it should be IRQ_TYPE_EDGE_RISING. Most of the time the distinction shouldn't matter, but there is a small possibility of losing interrupts unless it is corrected.
