Merge tag 'mmc-v5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc

Pull MMC updates from Ulf Hansson:
 "There are no updates for the MEMSTICK subsystem this time. But note
  that I am also carrying a patch from the pinctrl tree, which has been
  shared through an immutable branch.

  Summary:

  MMC core:
   - Convert to reasonable timeouts for all CMD6 commands (updates for
     BKOPS, CACHE_FLUSH and INAND_CMD38_ARG_EXT_CSD) for eMMC
   - Respect f_max clock rate at card initialization
   - Add gpiod_toggle_active_low() API
   - Consolidate slot-gpio code by using gpiod_toggle_active_low()

  MMC host:
   - Add pinctrl_select_default_state() API
   - Consolidate pintctrl code by using pinctrl_select_default_state()
   - mmci: Support any block sizes for SDIO for some variants
   - mmci: Enable reset control for stm32_sdmmc
   - mmc_spi: Toggle SPI_CS_HIGH polarity rather than hard-coding it
   - renesas_sdhi: Add support for the r8a77961 variant
   - renesas_sdhi: A few minor improvements
   - rockchip-dw-mshc: Add support for the rk3308 variant
   - sdhci: Enable support for external DMA controllers
   - sdhci: Fixup error path when sending CMD12
   - sdhci-brcmstb: Add support for 7216b0 variant
   - sdhci-brcmstb: Add support for command queuing (CQHCI)
   - sdhci-brcmstb: Add support for eMMC HS400ES mode
   - sdhci-msm: Add support for the sc7180 variant
   - sdhci-msm: Add support for command queuing (CQHCI)
   - sdhci-of-at91: Add support for the SAM9x60 variant
   - sdhci-of-at91: Improve support for tunings
   - sdhci-of-esdhc: A few fixups for some clock related issues
   - sdhci-omap: Add support for the am335x and the am437x variants
   - sdhci-omap: Improve support for erase operations
   - sdhci-omap: Add support for external DMA"
