* 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: "brcm,bcm7425-sdhci"
|
||||
|
||||
Refer to clocks/clock-bindings.txt for generic clock consumer properties.
|
||||
|
||||
Example:
|
||||
|
||||
sdhci@f03e0100 {
|
||||
compatible = "brcm,bcm7425-sdhci";
|
||||
reg = <0xf03e0000 0x100>;
|
||||
interrupts = <0x0 0x26 0x0>;
|
||||
sdhci,auto-cmd12;
|
||||
clocks = <&sw_sdio>;
|
||||
sd-uhs-sdr50;
|
||||
sd-uhs-ddr50;
|
||||
};
|
||||
|
||||
sdhci@f03e0300 {
|
||||
non-removable;
|
||||
bus-width = <0x8>;
|
||||
compatible = "brcm,bcm7425-sdhci";
|
||||
reg = <0xf03e0200 0x100>;
|
||||
interrupts = <0x0 0x27 0x0>;
|
||||
sdhci,auto-cmd12;
|
||||
clocks = <sw_sdio>;
|
||||
mmc-hs200-1_8v;
|
||||
};
