mmc: sdhci-acpi: enable runtime-pm for device HID INT33C6
sdhci-acpi supports ACPI devices which have compatibility ID PNP0D40, however it is not possible to know if those devices will all work correctly with runtime-pm, so that must be configured per hardware ID. 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 <adrian.hunter@intel.com> Acked-by: Chris Ball <cjb@laptop.org> Signed-off-by: Rafael J.
