This patch series adds busy detect for stm32 sdmmc variant.
Some adaptations are required:
-Avoid to check and poll busy status when is not expected.
-Clear busy status bit if busy_detect_flag and busy_detect_mask are
different.
-Add hardware busy timeout with MMCIDATATIMER register.
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: fix clear of busy detect status

Ludovic, just wanted to let you know that I am reviewing and testing
this series.
However, while running some tests on Ux500 for validating the busy
detection code, even without your series applied, I encounter some odd
behaviors. I am looking into the problem to understand better and will
let you know as soon as I have some more data to share.
Oops, don't hesitate to share your status, if I could help.
Kind regards
Uffe
