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()"
