Pull MMC fixes from Ulf Hansson:
 "MMC core:
   - Disable card detect during shutdown

  MMC host:
   - mmci: Fixup tuning support for stm32_sdmmc
   - meson-mx-sdhc: Fix support for multi-block SDIO commands
   - sdhci-tegra: Fix support for eMMC HS400ES mode"

* tag 'mmc-v5.16-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc:
  mmc: mmci: stm32: clear DLYB_CR after sending tuning command
  mmc: meson-mx-sdhc: Set MANUAL_STOP for multi-block SDIO commands
