   - sdhci-omap: Add support for controller in k2g SoC
   - sdhci-omap: Add workarounds for a couple of Erratas
   - sdhci-omap: Enable support for generic sdhci DT properties
   - sdhci-cadence: Re-send tune request to deal with errata
   - sdhci-pci: Fix 3.3V voltage switch for some BYT-based Intel controllers
   - sdhci-pci: Avoid 3.3V signaling on some NI 904x
   - sdhci-esdhc-imx: Use watermark levels for PIO access
   - sdhci-msm: Improve card detection handling
   - sdhci-msm: Add support voltage pad switching"
