From 66e45351f7d6798751f98001d1fcd572024d87f0 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit hkallweit1@gmail.com Date: Thu, 9 Feb 2023 21:11:47 +0100 Subject: [PATCH] arm64: dts: meson-gx: Make mmc host controller interrupts level-sensitive
The usage of edge-triggered interrupts lead to lost interrupts under load, see [0]. This was confirmed to be fixed by using level-triggered interrupts. The report was about SDIO. However, as the host controller is the same for SD and MMC, apply the change to all mmc controller instances.
