[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ludovic Barre <ludovic.barre@xxxxxx>

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
