From c72238ca3607996ab56357a02099df0744000726 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Thu, 26 Jan 2023 15:03:17 +0100 Subject: [PATCH] arm64: dts: amlogic: 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.
