Subject: [PATCH] arm64: dts: meson-gx: Make mmc host controller interrupts level-sensitive
Git-commit: 66e45351f7d6798751f98001d1fcd572024d87f0
Patch-mainline: v6.2-rc8
References: git-fixes
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.
