Subject[PATCH V3 0/3] mmc: mmci: add busy detect for stm32 sdmmc variant
From: Ludovic Barre <>

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
-Add hardware busy timeout with MMCIDATATIMER register.

-rebase on latest mmc next
-replace re-read by status parameter.

-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
