Merge tag 'mmc-v5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc

Pull MMC updates from Ulf Hansson:
 "MMC core:
   - Fixup max_discard/trim calculations
   - Announce SD specs greater than 4.0
   - Add discard support for SD cards
   - Don't do retries for CMD6 (SWITCH command)
   - Various cleanups and re-structuring

  MMC host:
   - cqhci:
      * Add maintainers for eMMC CQHCI driver
   - sdhci:
      * Consolidate WP GPIO code
      * Add ADMA3 DMA support for V4 enabled host
      * Fixup card detect support in pci-o2micro driver
      * Add support for CMDQ and SDMMC pads auto-calibration in tegra
        driver
      * Add DCMD support and CMDQ support, support for i.MX6ULL variant,
        fixup HS400 timing issue and add HS400_ES support for i.MX8QXP
        to esdhc-imx driver
      * Avoid CRC errors by adjusting settings to speed mode and fixup
        card initialization for high speed mode in renesas_sdhi
      * Fixup timeout settings for omap
      * Enable 8 bits bus-width support in atmel-mci
      * Convert some legacy code in jz4740 driver to use modern APIs
      * Send a CMD12 to clear DPSM at errors for STM32 sdmmc mmci
        driver"
