From: Ludovic Barre <ludovic.barre@st.com>
This patch series adds busy detect for stm32 sdmmc variant. Some adaptations are required: -On sdmmc the data timer is started on data transfert and busy state, so we must add hardware busy timeout support. -Add busy_complete callback at mmci_host_ops to allow to define a specific busy completion by variant. -Add sdmmc busy_complete calback.
V5: -Replaces !cmd->data to !host->mrq->data to avoid overwrite of datatimer register by the first command (cmd23, without data) of SBC request.
V4: -Re-work with busy_complete callback -In series, move "mmc: mmci: add hardware busy timeout feature" in first to simplify busy_complete prototype with err_msk parameter.
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
