SDIO specification defines that the interrupt is level-sensitive. Fix the interrupt trigger type for emmc_a accordingly. See comment at beginning of the file wrt which is the SDIO port. mmc2 = &sd_emmc_a; /* SDIO */ 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. Note: SDIO interrupt support was added in Linux just recently, however other users of this dts may be affected too.
