Merge tag 'mmc-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc

Pull MMC updates from Ulf Hansson:
 "These are the updates for MMC and MEMSTICK for v5.5.

  Note that this also contains quite some additional changes reaching
  beyond both the MMC and MEMSTICK subsystems. This is primarily because
  of fixing an old regression for a WiFi driver based on the SDIO
  interface on an OMAP openpandora board

  MMC core:
   - Add CMD13 polling for MMC IOCTLS with R1B response.
   - Add common DT properties for clk-phase-delays for various speed
     modes.
   - Fix size overflow for mmc gp-partitions.
   - Re-work HW reset for SDIO cards, which also includes a re-work for
     Marvell's WiFi mwifiex SDIO func driver.

  MMC host:
   - jz4740: Add support for X1000 and JZ4760.
   - jz4740: Add support for 8-bit bus and for low power mode.
   - mmci: Add support for HW busy timeout for the stm32_sdmmc variant.
   - owl-mmc: Add driver for Actions Semi Owl SoCs SD/MMC controller.
   - renesas_sdhi: Add support for r8a774b1.
   - sdhci_am654: Add support for Command Queuing Engine for J721E.
   - sdhci-milbeaut: Add driver for the Milbeaut SD controller.
   - sdhci-of-arasan: Add support for ZynqMP tap-delays.
   - sdhci-of-arasan: Add support for clk-phase-delays for SD cards.
   - sdhci-of-arasan: Add support for Intel LGM SDXC.
   - sdhci-of-aspeed: Allow inversion of the internal card detect
     signal.
   - sdhci-of-esdhc: Fixup workaround for erratum A-008171 for tunings.
   - sdhci-of-at91: Improve support for calibration.
   - sdhci-pci: Add support for Intel JSL.
   - sdhci-pci: Add quirk for AMD SDHC Device 0x7906.
   - tmio: Enable support for erase/discard/trim requests.

  MMC/OMAP/pandora/wl1251:

  The TI wl1251 WiFi driver for SDIO on the OMAP openpandora board has
  been broken since v4.7. To fix the problems, changes have been made
  cross subsystems, but also to OMAP2 machine code and to openpandora
  DTS files, as summarized below. Relevant changes have been tagged for
  stable.

   - mmc/wl1251: Re-introduce lost SDIO quirks and vendor-id for wl1251
   - omap/omap_hsmmc: Remove redundant platform config for openpandora
   - omap_hsmmc: Initialize non-std SDIO card for wl1251 for pandora
   - omap/dts/pandora: Specify wl1251 through a child node of mmc3
   - wl1251: Add devicetree support for TI wl1251 SDIO"
