   3 This file documents differences between the core properties in mmc.txt
   4 and the properties used by the sdhci-brcmstb driver.
   5
   6 NOTE: The driver disables all UHS speed modes by default and depends
   7 on Device Tree properties to enable them for SoC/Board combinations
   8 that support them.
   9
  10 Required properties:
  11 - compatible: should be one of the following
  12   - "brcm,bcm7425-sdhci"
  13   - "brcm,bcm7445-sdhci"
  14   - "brcm,bcm7216-sdhci"

  16 Refer to clocks/clock-bindings.txt for generic clock consumer properties.
