Merge tag 'mmc-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc
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"
