From d182bcf300772d8b2e5f43e47fa0ebda2b767cc4 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Thu, 9 Feb 2023 21:10:31 +0100 Subject: [PATCH] arm64: dts: meson-axg: 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.
