   - Various code quality improvements, especially for slot-gpio.

  MMC host:
   - dw_mmc: Various fixes and cleanups.
   - dw_mmc: Convert to mmc_send_tuning().
   - moxart: Fix probe logic.
   - sdhci: Various fixes and cleanups
   - sdhci: Asynchronous request handling support.
   - sdhci-pxav3: Various fixes and cleanups.
   - sdhci-tegra: Fixes for T114, T124 and T132.
   - rtsx: Various fixes and cleanups.
   - rtsx: Support for SDIO.
   - sdhi/tmio: Refactor and cleanup of header files.
   - omap_hsmmc: Use slot-gpio and common MMC DT parser.
