For some of the ST-variants, card busy detection on the DAT0 pin is supported. We extend the variant struct with a busy_detect flag to indicate support for it. A corresponding busy detect function, which polls the busy status bit, is then set to the .card_busy callback. Signed-off-by: Ulf Hansson Signed-off-by: Russell King --- Reading git-diff-tree failed
