1* BROADCOM BRCMSTB/BMIPS SDHCI Controller
2
3This file documents differences between the core properties in mmc.txt
4and the properties used by the sdhci-brcmstb driver.
5
6NOTE: The driver disables all UHS speed modes by default and depends
7on Device Tree properties to enable them for SoC/Board combinations
8that support them.

10Required properties:
11- compatible: should be one of the following
12  - "brcm,bcm7425-sdhci"
13  - "brcm,bcm7445-sdhci"
14  - "brcm,bcm7216-sdhci"
15
16Refer to clocks/clock-bindings.txt for generic clock consumer properties.
