For INT33C6, several related quirks, capabilities and flags are set: MMC_CAP_NONREMOVABLE The SDIO card will never be removable SDHCI_ACPI_RUNTIME_PM Enable runtime-pm of the host controller MMC_CAP_POWER_OFF_CARD Enable runtime-pm of the SDIO card MMC_PM_KEEP_POWER SDIO card has the capability to remain powered up during system suspend SDHCI_QUIRK2_HOST_OFF_CARD_ON Always do a full reset during system resume because the card may be already initialized having not been powered off. Wake-ups from the INT33C6 host controller are not supported, so the following capability must *not* be set: MMC_PM_WAKE_SDIO_IRQ Enable wake on card interrupt Signed-off-by: Adrian Hunter Acked-by: Chris Ball --- drivers/mmc/host/sdhci-acpi.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/mmc/host/sdhci-acpi.c b/drivers/mmc/host/sdhci-acpi.c index 6ac3617..12b0a78 100644 --- a/drivers/mmc/host/sdhci-acpi.c +++ b/drivers/mmc/host/sdhci-acpi.c @@ -87,7 +87,15 @@ static const struct sdhci_ops sdhci_acpi_ops_dflt = { .enable_dma = sdhci_acpi_enable_dma, }; +static const struct sdhci_acpi_slot sdhci_acpi_slot_int_sdio = { + .quirks2 = SDHCI_QUIRK2_HOST_OFF_CARD_ON, + .caps = MMC_CAP_NONREMOVABLE | MMC_CAP_POWER_OFF_CARD, + .flags = SDHCI_ACPI_RUNTIME_PM, + .pm_caps = MMC_PM_KEEP_POWER, +}; + static const struct acpi_device_id sdhci_acpi_ids[] = { + { "INT33C6", (kernel_ulong_t)&sdhci_acpi_slot_int_sdio }, { "PNP0D40" }, { }, };
