Subject: [PATCH] arm64: dts: meson-g12-common: Make mmc host controller interrupts level-sensitive
Git-commit: ac8db4cceed218cca21c84f9d75ce88182d8b04f
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.
