* BROADCOM BRCMSTB/BMIPS SDHCI Controller
|
|
|
|
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
|
|
- "brcm,bcm7425-sdhci"
|
|
- "brcm,bcm7445-sdhci"
|
|
- "brcm,bcm7216-sdhci"
|
|
|
|
Refer to clocks/clock-bindings.txt for generic clock consumer properties.
