Pull MMC updates from Ulf Hansson:
 "MMC core:
   - Add support to enable irq wake for slot gpio
   - Remove MMC_CAP2_HC_ERASE_SZ and make it the default behaviour
   - Improve R1 response error checks for stop commands
   - Cleanup and clarify some MMC specific code
   - Keep card runtime resumed while adding SDIO function devices
   - Use device_property_read instead of of_property_read in mmc_of_parse()
   - Move boot partition locking into a driver op to enable proper I/O scheduling
   - Move multi/single-ioctl() to use block layer to enable proper I/O scheduling
   - Delete bounce buffer Kconfig option
   - Improve the eMMC HW reset support provided via the eMMC pwrseq
   - Add host API to manage SDIO IRQs from a workqueue

  MMC host:
   - dw_mmc: Drop support for multiple slots
   - dw_mmc: Use device_property_read instead of of_property_read
   - dw_mmc-rockchip: Optional improved tuning to greatly decrease tuning time
   - dw_mmc: Prevent rpm suspend for SDIO IRQs instead of always for SDIO cards
   - dw_mmc: Convert to use MMC_CAP2_SDIO_IRQ_NOTHREAD for SDIO IRQs
   - omap_hsmmc: Convert to mmc regulator APIs to consolidate code
   - omap_hsmmc: Deprecate "vmmc_aux" in DT and use "vqmmc" instead
   - tmio: make sure SDIO gets reinitialized after resume
   - sdhi: add CMD23 support to R-Car Gen2 & Gen3
   - tmio: add CMD23 support
   - sdhi/tmio: Refactor code and rename files to simplify Kconfig options
   - sdhci-pci: Enable card detect wake for Intel BYT-related SD controllers
   - sdhci-pci: Add support for Intel CNP
   - sdhci-esdhc-imx: Remove ENGcm07207 workaround - allow multi block transfers
   - sdhci-esdhc-imx: Allow all supported prescaler values
   - sdhci-esdhc-imx: Fix DAT line software reset
   - sdhci-esdhc: Add SDHCI_QUIRK_32BIT_DMA_ADDR
   - atmel-mci: Drop AVR32 support"
