Pull MMC updates from Chris Ball: Core: * Support for MMC 4.5 Data Tag feature -- we tag REQ_META, so devices that support Data Tag will provide increased throughput for metadata. * Faster detection of card removal on I/O errors. Drivers: * dw_mmc now supports eMMC Power Off Notify, has PCI support, and implements pre_req and post_req for asynchronous requests. * omap_hsmmc now supports device tree. * esdhc now has power management support. * sdhci-tegra now supports Tegra30 devices. * sdhci-spear now supports hibernation. * tmio_mmc now supports using a GPIO for card detection. * Intel PCH now supports 8-bit bus transfers. * tag 'mmc-merge-for-3.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc: (53 commits) mmc: sh_mmcif: simplify bitmask macros mmc: sh_mobile_sdhi: support modular mmc-core with non-standard hotplug mmc: sh_mobile_sdhi: add a callback for board specific init code mmc: tmio: cosmetic: prettify the tmio_mmc_set_ios() function mmc: sh_mobile_sdhi: do not manage PM clocks manually mmc: tmio_mmc: remove unused sdio_irq_enabled flag mmc: tmio_mmc: power status flag doesn't have to be exposed in platform data mmc: sh_mobile_sdhi: pass card hotplug GPIO number to TMIO MMC mmc: tmio_mmc: support the generic MMC GPIO card hotplug helper mmc: tmio: calculate the native hotplug condition only once mmc: simplify mmc_cd_gpio_request() by removing two parameters mmc: sdhci-pci: allow 8-bit bus width for Intel PCH mmc: sdhci: check interrupt flags in ISR again mmc: sdhci-pci: Add MSI support mmc: core: warn when card doesn't support HPI mmc: davinci: Poll status for small size transfers mmc: davinci: Eliminate spurious interrupts mmc: omap_hsmmc: Avoid a regulator voltage change with dt mmc: omap_hsmmc: Convert hsmmc driver to use device tree mmc: sdhci-pci: add SDHCI_QUIRK2_HOST_OFF_CARD_ON for Medfield SDIO ...
