Revision ac8db4cceed218cca21c84f9d75ce88182d8b04f authored by Heiner Kallweit on 09 February 2023, 20:11:10 UTC, committed by Neil Armstrong on 10 February 2023, 08:02:09 UTC
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.
