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

Pull MMC updates from Ulf Hansson:
 "MMC core:
   - Let the dma map ops deal with bouncing and drop dma_max_pfn() from
     the dma-mapping interface for ARM
   - Convert the generic MMC DT doc to YAML schemas
   - Drop questionable support for powered-on re-init of SDIO cards at
     runtime resume and for SDIO HW reset
   - Prevent questionable re-init of powered-on removable SDIO cards at
     system resume
   - Cleanup and clarify some SDIO core code

  MMC host:
   - tmio: Make runtime PM enablement more flexible for variants
   - tmio/renesas_sdhi: Rename DT doc tmio_mmc.txt to renesas,sdhi.txt
     to clarify
   - sdhci-pci: Add support for Intel EHL
   - sdhci-pci-o2micro: Enable support for 8-bit bus
   - sdhci-msm: Prevent acquiring a mutex while holding a spin_lock
   - sdhci-of-esdhc: Improve clock management and tuning
   - sdhci_am654: Enable support for 4 and 8-bit bus on J721E
   - sdhci-sprd: Use pinctrl for a proper signal voltage switch
   - sdhci-sprd: Add support for HS400 enhanced strobe mode
   - sdhci-sprd: Enable PHY DLL and allow delay config to stabilize the
     clock
   - sdhci-sprd: Add support for optional gate clock
   - sunxi-mmc: Convert DT doc to YAML schemas
   - meson-gx: Add support for broken DRAM access for DMA

  MEMSTICK core:
   - Fixup error path of memstick_init()"
