On AP4EVB the card detect pin of the top SD/MMC slot is not directly connected
to the tmio/mmcif controller but to a GPIO pin, so polling needs to be done for
SDHI1 and MMCIF in order to support hotplug for that slot. SHDI1 and MMCIF
share that slot, and the used controller is selected by a DIP swi
In some platforms (e.g. AP4EVB) the card detect pin of a slot is not directly
connected to the sh_mmcif controller, so that polling needs to be used. To
overcome the overhead induced by querying the controller on each poll cycle,
card detection can be handled in the platform code more efficiently.
On some platforms (e.g. AP4EVB) the card detect pin of a slot is not directly
connected to the sdhi hardware, so that polling needs to be used with tmio_mmc
and card detection is handled in the platform code.
This patch allows to set tmio_mmc capabilities (to pass the MMC_CAP_NEEDS_POLL
flag) and e
Some controllers, supported by the tmio_mmc driver do not have the card detect
pin of a slot connected, so that polling needs to be used and card detection is
handled by other means.
This patch exposes a get_cd hook for that purpose.

This patch series attempts to fix hotplug (for sh_mobile_sdhi/tmio_mmc) and
improve hotplug (for sh_mmcif) on the AP4EVB (shmobile) board, by handling the
card detect in platform code.
Best regards,

Hello,
testing the sdhci-stm.c driver, I sent some weeks ago to the mailing list,
I'm facing some performance issues.
For example, when copy a file (e.g. ~10MiB) to the card, I've noticed that,
in the sdhci_prepare_data, the maximum value for data->blocks is 248.
The sdhci-stm driver uses the ADMA
