> 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 callback.
> 
> V6:
> -mmci_start_command: set datatimer only on rsp_busy flag
> (remove host->mrq->data).
> -move max_busy_timeout in set_ios callback.
> -typo fix: err_msk, clks on one lines.
> 
> 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
