Hi,

These 2 patches seem to have fallen through the crack, so I'm
resending them. They have been rebased on top of 4.11-rc1 (trivial
rebase).

Regards,

Hans

The sdhci_intel_byt_* and the non _qcom_ sdhci_acpi_slot_ entries in
sdhci-acpi.c are for the same mmc host in either pci or acpi mapped
mode, so the flags should be the same.

The syncing removes the SDHCI_QUIRK_BROKEN_CARD_DETECTION quirk from
sdhci_acpi_slot_int_sdio, this quirk is a nop as this slot also has
MMC_CAP_NONREMOVABLE, and adds SDHCI_QUIRK2_PRESET_VALUE_BROKEN to
sdhci_acpi_slot_int_sdio and sdhci_acpi_slot_int_sd. Note that
sdhci_acpi_slot_int_mmc already has the SDHCI_QUIRK2_PRESET_VALUE_BROKEN
quirk, which is another indication that the others need it too.

SDIO cards may need clock to send the card interrupt to the host.
Set SDHCI_QUIRK2_CARD_ON_NEEDS_BUS_ON to prevent the clock resource
being released.

Hans de Goede:

It looks like we still need this patch, on a cherrytrail tablet with
a RTL8723BS wifi chip, without this patch pinging the tablet results in:

Where as with this patch I get:

Note an alternative approach would be to add a new flag for this and do
a runtime_pm_get on sdio_irq_enable and runtime_pm_put on
sdio_irq_disable, that would safe some power if the sdio-driver properly
disables the irq when e.g. wifi is turned off, or an oob interrupt is
used.

That approach seems more reasonable. Can you please try this instead?

Ok, done (just completed testing it) I will send a v2 of this set
with that approach right after this mail.
