V2: -mmci_cmd_irq cleanup in separate patch. -simplify the busy_detect_flag exclude -replace sdmmc specific comment in "mmc: mmci: avoid fake busy polling in mmci_irq" to focus on common behavior Ludovic Barre (5): mmc: mmci: cleanup mmci_cmd_irq for busy detect feature mmc: mmci: avoid fake busy polling in mmci_irq mmc: mmci: fix clear of busy detect status mmc: mmci: add hardware busy timeout feature mmc: mmci: add busy detect for stm32 sdmmc variant drivers/mmc/host/mmci.c | 61 ++++++++++++++++++++++++++++++++++++++----------- drivers/mmc/host/mmci.h | 3 +++ 2 files changed, 51 insertions(+), 13 deletions(-) -- 2.7.4
