The i.MX ESDHC driver uses SDHCI_QUIRK2_CAPS_BIT63_FOR_HS400. With that the stack checks bit 63 to descide whether HS400 is available. Using sdhci-caps-mask allows to mask bit 63. The stack then selects HS200 as operating mode. This prevents rare communication errors with minimal effect on performance: sdhci-esdhc-imx 30b60000.usdhc: warning! HS400 strobe DLL status REF not lock!
