Merge tag 'mmc-v5.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc 

Pull MMC fixes from Ulf Hansson:
 "MMC core:
   - Fix init of SD cards reporting an invalid VDD range

  MMC host:
   - sprd: Fixes for clocks, card-detect, write-protect etc
   - cadence: Fix ADMA 64-bit addressing
   - tegra: Re-allow writing to SD card when GPIO pin is absent
   - at91: Fix eMMC init by clearing HS200 cap as it's not supported"

* tag 'mmc-v5.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc:
  mmc: sdhci-cadence: enable v4_mode to fix ADMA 64-bit addressing
  mmc: sdhci-sprd: clear the UHS-I modes read from registers
  mms: sdhci-sprd: add SDHCI_QUIRK_BROKEN_CARD_DETECTION
  mmc: sdhci-sprd: add SDHCI_QUIRK2_PRESET_VALUE_BROKEN
  mmc: sdhci-sprd: add get_ro hook function
  mmc: sdhci-sprd: fixed incorrect clock divider
  mmc: core: Fix init of SD cards reporting an invalid VDD range
  mmc: sdhci-of-at91: add quirk for broken HS200
  Revert "mmc: sdhci-tegra: drop ->get_ro() implementation"
