Merge tag 'mmc-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc

Pull MMC updates from Ulf Hansson:
 "This time, this pull request contains changes crossing subsystems and
  archs/platforms, which is mainly because of a bigger modernization of
  moving from legacy GPIO to GPIO descriptors for MMC (by Linus
  Walleij).

  Additionally, once again, I am funneling changes to
  drivers/misc/cardreader/* and drivers/memstick/* through my MMC tree,
  mostly due to that we lack a maintainer for these.

  Summary:

  MMC core:
   - Cleanup BKOPS support
   - Introduce MMC_CAP_SYNC_RUNTIME_PM
   - slot-gpio: Delete legacy slot GPIO handling

  MMC host:
   - alcor: Add new mmc host driver for Alcor Micro PCI based cardreader
   - bcm2835: Several improvements to better recover from errors
   - jz4740: Rework and fixup pre|post_req support
   - mediatek: Add support for SDIO IRQs
   - meson-gx: Improve clock phase management
   - meson-gx: Stop descriptor on errors
   - mmci: Complete the sbc error path by sending a stop command
   - renesas_sdhi/tmio: Fixup reset/resume operations
   - renesas_sdhi: Add support for r8a774c0 and R7S9210
   - renesas_sdhi: Whitelist R8A77990 SDHI
   - renesas_sdhi: Fixup eMMC HS400 compatibility issues for H3 and M3-W
   - rtsx_usb_sdmmc: Re-work card detection/removal support
   - rtsx_usb_sdmmc: Re-work runtime PM support
   - sdhci: Fix timeout loops for some variant drivers
   - sdhci: Improve support for error handling due to failing commands
   - sdhci-acpi/pci: Disable LED control for Intel BYT-based controllers
   - sdhci_am654: Add new SDHCI variant driver to support TI's AM654 SOCs
   - sdhci-of-esdhc: Add support for eMMC HS400 mode
   - sdhci-omap: Fixup reset support
   - sdhci-omap: Workaround errata regarding SDR104/HS200 tuning failures
   - sdhci-msm: Fixup sporadic write transfers issues for SDR104/HS200
   - sdhci-msm: Fixup dynamical clock gating issues
   - various: Complete converting all hosts into using slot GPIO descriptors

  Other:
   - Move GPIO mmc platform data for mips/sh/arm to GPIO descriptors
   - Add new Alcor Micro cardreader PCI driver
   - Support runtime power management for memstick rtsx_usb_ms driver
   - Use USB remote wakeups for card detection for rtsx_usb misc driver"
