Hi, When using omap_hsmmc driver, if sd-card repeatedly plug unplugged multiple times quickly, card enumeration stops after few iterations. This can be easily reproduced on DRA74X EVM which uses omap_hsmmc driver. This patch series addresses the above problem. The first patch fixes irq handler to report all DTOs to mmc-core. Second patch adds handling for BADA, DEB and CEB interrupts. The last patch introduces driver specific card detect irq handler to cleanup pending requests before card removal. Tested on DRA74X amd DRA72X and AM437X-GP EVMs, by repeated intense plug/unplug iterations.
