It supports up to HS400HS mode. The only peculiarity of the hardware is that it needs the preset value quirk to configure the clock properly at speed slower than HS200. This patchset adds a compatible device tree binding to cdns sdhci for mobileye then uses it in the sdhci-cadence driver. It also adds an emmc entry in the dtsi of each SoC and the config options in each defconfig to allow using an eMMC for the rootfs.
