-This file documents differences between the core properties in mmc.txt
-and the properties used by the sdhci-brcmstb driver.
-
-NOTE: The driver disables all UHS speed modes by default and depends
-on Device Tree properties to enable them for SoC/Board combinations
-that support them.
-
-Required properties:
-- compatible: should be one of the following
