From: Ludovic Barre <[email protected]> The "busy_detect_flag" is used to read/clear busy value of mmci status. The "busy_detect_mask" is used to manage busy irq of mmci mask. For sdmmc variant, the 2 properties have not the same offset. To clear the busyd0 status bit, we must add busy detect flag, the mmci mask is not enough.
