From: Ludovic Barre <[email protected]> This patch series adds busy detect for stm32 sdmmc variant. Some adaptations are required: -Clear busy status bit if busy_detect_flag and busy_detect_mask are different. -Add hardware busy timeout with MMCIDATATIMER register.
V3: -rebase on latest mmc next -replace re-read by status parameter. 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 (3): mmc: mmci: fix read status for busy detect mmc: mmci: add hardware busy timeout feature mmc: mmci: add busy detect for stm32 sdmmc variant drivers/mmc/host/mmci.c | 49 +++++++++++++++++++++++++++++++++++++++++-------- drivers/mmc/host/mmci.h | 3 +++ 2 files changed, 44 insertions(+), 8 deletions(-) -- 2.7.4
