Merge tag 'mmc-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc

Pull MMC and MEMSTICK updates from Ulf Hansson:
 "MMC core:
   - Fix hanging on I/O during system suspend for removable cards
   - Set read only for SD cards with permanent write protect bit
   - Power cycle the SD/SDIO card if CMD11 fails for UHS voltage
   - Issue a cache flush for eMMC only when it's enabled
   - Adopt to updated cache ctrl settings for eMMC from MMC ioctls
   - Use use device property API when parsing voltages
   - Don't retry eMMC sanitize cmds
   - Use the timeout from the MMC ioctl for eMMC santize cmds

  MMC host:
   - mmc_spi: Make of_mmc_spi.c resource provider agnostic
   - mmc_spi: Use polling for card detect even without voltage-ranges
   - sdhci: Check for reset prior to DMA address unmap
   - sdhci-acpi: Add support for the AMDI0041 eMMC controller variant
   - sdhci-esdhc-imx: Depending on OF Kconfig and cleanup code
   - sdhci-pci: Add PCI IDs for Intel LKF
   - sdhci-pci: Fix initialization of some SD cards for Intel BYT
   - sdhci-pci-gli: Various improvements for GL97xx variants
   - sdhci-of-dwcmshc: Enable support for MMC_CAP_WAIT_WHILE_BUSY
   - sdhci-of-dwcmshc: Add ACPI support for BlueField-3 SoC
   - sdhci-of-dwcmshc: Add Rockchip platform support
   - tmio/renesas_sdhi: Extend support for reset and use a reset controller
   - tmio/renesas_sdhi: Enable support for MMC_CAP_WAIT_WHILE_BUSY
   - tmio/renesas_sdhi: Various improvements

  MEMSTICK:
   - Minor improvements/cleanups"
